EFF is bringing the security and privacy of HTTPS Everywhere to an important new frontier: your Android phone. As of today, you can install HTTPS Everywhere on Firefox for Android (until now, it could only protect desktop browsers). With HTTPS Everywhere installed, Firefox for Android encrypts thousands of connections from your browser that would otherwise be insecure. This gives Firefox a huge security advantage over every other mobile browser available today.
This is exciting news, because HTTPS encryption allows smartphone users to safely download apps, browse the web, exchange emails and instant messages, sync data between devices, and countless other everyday tasks. As we carry around our phones and tablets, we often connect to unfamilar WiFi networks, putting our personal data at risk of being monitored, collected, and tampered with by anyone else on the same network, as well as Internet Service Providers, network operators, and government agencies. In fact, we discovered last week that NSA and GCHQ have been invisibly tracking and profiling users based on data leakage from smartphone apps.
HTTPS Everywhere guards agains these attacks in your browser by switching insecure HTTP connections to secure HTTPS connections whenever possible using thousands of URL rewrite rules. Whereas data sent to a server over HTTP can easily be read and modified by third parties, HTTPS uses strong encryption to guarantee data confidentiality and integrity.

Figured I'd share this with you guys. HTTPS Everywhere has been a great desktop Firefox addon, I'm really happy to see them finally get a mobile Firefox version out. Probably the best way this would protect people are when using public wifi, but of course the site you visit would have to offer some form of HTTPS/SSL for the addon to work. It basically just helps you get the most out of sites that do offer it (some sites, like Youtube for instance default to HTTP).
Hmmm.. interesting.... But does Https Everywhere still have the problem that because of it, pages in general load a lot slower?
I haven't noticed any slow down personally. All this does really is help sites that support HTTPS/SSL to some extent, but for whatever reason do not default to it when I user visits the page. And obviously they make sure the site doesn't get broken before adding it in their extension's site list.
There's a whole FAQ here too that might explain it better than I ever could. All I know is if Tor browsers use it along with Noscript, it's a good security add on. Way better than nothing.
https://www.eff.org/https-everywhere/faq
But the add on should also make use of their SSL Observatory, which is a measure in place to protect users:
The EFF SSL Observatory is a project to investigate the certificates used to secure all of the sites encrypted with HTTPS on the Web. We have downloaded datasets of all of the publicly-visible SSL certificates on the IPv4 Internet, in order to search for vulnerabilities, document the practices of Certificate Authorities, and aid researchers interested the web's encryption infrastructure.

Greetings all and Happy Holidays.
Per some fellow XDA users request and also to compliment the great thread "[TUTO] How To Secure Your Phone," by: unclefab, I figured this would help...a thread on VPN.
I am also shocked to not see anything in the security forum about VPN! I did a search and NOTHING.
What is a VPN?
(Virtual Private Network)
A simple search on the web will give you the nitty gritty stuff on what a VPN is, but I'll just lay it out very simply.
A VPN takes your data connection and encrypts it so it protects your data from not only your ISP seeing your traffic, but also from middle man attacks. Say if you were at a cafe connected to their open (unsecured) public WiFi and you did some shopping online, which involved you entering in your credit card number, name, address, etc... Well, it doesn't take much for someone to intercept your sensitive data passing through the cafe's unsecured WiFi connection.
How it works:
Encrypts your Computer's/Phone's data ---> Connects it to your VPN's server (Exit Server) ---> Then it reaches the end destination (website). (Safe Passage)
ie...
Safely passes your Internet Data, through a ---> [TUNNEL] ---> ...that is encrypted so that all your data is not only anonymous, but also protected.
There are may VPN's service providers out there, however, they are not all created equal. I've spent a lot of time researching VPN's and have went to great lengths to find the best of the best. The criteria of what I was looking for is as follows:
Offshore Company. Something outside of the US.
Liked and approved by even the extreme private/security activists.
Reliability and Speed! Some VPN's can be very slow only allowing you to achieve 30-50% of your internet speed at best.
A wide choice of servers.
Able to pay anonymously.
A VPN THAT WORKS ON OUR ANDROID DEVICES!
Some VPN companies have their own Android VPN client, which makes things a breeze. Just launch, connect and violla....all your traffic is now safely tunneled.
For the companies that do not have their own Android VPN client, you'll have to use the app: OpenVPN, which can be a hit or a miss for those on KK 4.4. Let me explain...
When I was on my Note 3 on 4.3, OpenVPN worked flawlessly and my speeds were darn near 100% of my regular LTE speeds even connected to a VPN! Well, once KK 4.4 came around, it completely ruined everything in terms of being able to stay connected. KK 4.4 is and was a nightmare for OpenVPN users. Upgrading from 4.3 to 4.4 was the biggest mistake I have ever made in my Android world. Bottom line, KK 4.4 sucks.
The good news is, there are a few VPN companies that work flawlessly on KK 4.4. I'm using one at the moment and it stays connected just fine with awesome speeds!
Why you should use a VPN:
Well think about. You can go the whole nine yards in securing your phone, which is awesome, but then you'd still be tunneling all that traffic "unencrypted," over the internet .... this is counter-intuitive in every way that you look at it. It's like ordering a BIG MAC Extra value meal and getting a diet coke. I mean really? What's the point? Diet? No matter how you see it, you're going to get fat if you keep eating it and thinking a diet coke is going to take edge off of you getting fat. Sorry, it doesn't work that way....
Imagine a semi-trucks driving down the highway with some completely exposed and some locked and covered. Well you'll obviously be able to see the exposed cargo on all the trucks that are not contained yes? Whereas the ones that are covered and locked, you'd have no clue what's in there. This is how a VPN works....it covers your data/traffic so that no one can see or know what is inside of that container during transit...ie...it provides a safe passage of your data over the internet to the end destination.
Now a VPN will protect your data from point A to the end destination (website.) That website will only be able to see your "exit server," and not your ISP or your location, but of course your data.
Ex: You're in New York connected to the internet using a VPN ----> The VPN server you're connected to is in Texas ---> The website you're visiting is located and hosted in Canada.
In that example, your "encrypted" data/traffic is being routed through Texas and then to Canada where the website is hosted/located. Make sense?
Because you're connecting to a VPN server, this is why you have to know which ones to use so that you can trust your data routing through their servers. Not all VPN companies are created equal!
If you're interested to know which VPN's are best in general and for our Android devices, PM me and I'll share with you my research. I don't want to advertise anything on here to be in compliance with the forum rules.
I hope this helps!

You forgot to tell the data is not encrypted by the VPN between it's server and the website's server, you are only moving a problem from place A to place B. It may be better for you if this is what you are looking for but it doesn't add that much security.
How a VPN works : Your device data is encrypted FIRST, it leaves your device and goes to the VPN's server, it is DECRYPTED, and then it is relayed to the server you were trying to contact. Your data is less traceable but you're not anonymous, the VPN provider knows who you are and your DNS provider may still know what you are looking at if you the device leak DNS requests.
Your guide is missing details, anonymity and security is not easy and trying to simplify it too much you lost important parts users should not forget.

Misleading? I think you need to re-read the post. Here let me help you:
"A VPN takes your data connection and encrypts it so it protects your data from not only your ISP seeing your traffic, but also from middle man attacks. Say if you were at a cafe connected to their open (unsecured) public WiFi and you did some shopping online, which involved you entering in your credit card number, name, address, etc...

"Now a VPN will protect your data from point A to the end destination (website.) That website will only be able to see your "exit server," and not your ISP or your location, but of course your data."
"Ex: You're in New York connected to the internet using a VPN ----> The VPN server you're connected to is in Texas ---> The website you're visiting is located and hosted in Canada."
So you're going to argue the fact that a VPN wouldn't be affective in a cafe scenario like the example I've given in the post?
Any additional information is appreciated, but please don't come in here saying that it's misleading....
THE FACT IS...YOU'RE BETTER OFF WITH A VPN, than WITHOUT ONE. PERIOD.
It's about trust, the VPN server can do the middle man attack itself or one could do it somewhere between the VPN's server and the final destination.
Of course you're better with a VPN most of the time, but it's important to clearly state it's not captain america's shield neither. It's important to clearly tell at all cost that the data is encrypted only between you and the VPN's server.
Best regards.
The only way to ensure you are safe from MITM is to use end to end encryption, like SSL/TLS (https). Even if the MITM is using sslstrip, you'll be able to tell by the security popup in your browser when it asks you to trust the connection (which you shouldn't...)
VPN is useful for protecting you from someone sniffing the airwaves on an open network or for accessing services behind a firewalled network. (Like SMB/Windows File Sharing).
Like Magissa said, it isn't captain America's shield, and don't be fooled by a false sense of security. You have to trust the VPN provider, and it would be pretty easy for one to sniff your traffic or read logs...

There's no concrete answer to that question. Your best bet is to use a VPN provider that's based outside of your country, preferably one that is less likely to corporate with your local law enforcement.
Agreed. Out of country, away from your government's reach... There are some offshore server farms in countries with lax laws... Those are usually tax havens also. Research

Thanks bro for the info.
I have always known that companies like google and facebook for example collect our data, web searches etc and sell this information for profit. Today, this has become an even bigger issue with what we see in the media with the nsa and other government organizations tapping into our devices and monitoring our usage. At the end of the day, most of us, myself included really dont have anything to hide, so it may not be a real issue. I have often thought that if anyone poked around in my pc or phone they would simply get bored as they are just full of geeky engineering files lol. The real thing for me is simply that it's an invasion of privacy and just not right. With that said, I find myself wanting to go the extra mile to make my pc and my phone completely private from outside sources taking my information, watching my web searches and seeing my data. My question is, is it possible to be 100% secure and private, and if not, how close can we get, and how? I have heard that VPN's can achieve this. Is this true? and if so are there any free secure VPN's for our android devices and or pc's that are really good? Do VPN's slow down our devices? Also, Is there a way when we delete android files to permanently delete them? I noticed when I flashed my rom, after doing the complete wipe that is still contains files from before the wipe.
(I know this isn't a pc forum, I only included the pc because it's relevant.)
Thank you all in advance.
There are no data retention laws in the United States. Meaning, if a data center does not want to hold any logs to their users' activity, they're not required by law to do so. Multiple countries are similar, which is why I recommend using Private Internet Access for your VPN. They have a client for PC and Android and they're really great. I've been using them for many years and have had no issues. And, if you're really wanting to remain "anonymous", you can pay for your VPN subscription using gift cards from popular outlets like Walmart, Starbucks, etc. And for search engines, I'd recommend DuckDuckGo, which doesn't log anything you search. For PC, I'd recommend disabling your IPv6 protocol in your router settings and getting uBlock Origin, HTTPS Everywhere, and PrivacyBadger. They're wonderful add-ons for Firefox or Chrome. uBlock Origin and PrivacyBadger can block WebRTC leaks which would leak your IP address and can be used to identify you. If you want more information, feel free to reply to my post and I'll help you out as much as I can.

Hoxic,
Thank you for all of the information. With the private internet access VPN on my PC and android, will that slow down anything like web surfing, uploads or downloads? I am limited to using Verizon's high speed DSL connection as they refer to it, (I refer to it as slowest speed connection lol) in my neighborhood and this is the only provider for me so it's already pretty slow compared to Fios and other broadband connections. I would hate to slow it down any more.
You mention to pay for these services using gift cards and such. Well as I mentioned, I do not have anything that I am actually worried about anyone seeing, this is simply my way of trying to protect my privacy so I wouldn't go that far but I am curious about that statement. Do you mean that using a VPN truly isn't private or is this just to remove any paper trail linking me to the use of a VPN provider? I have been using DuckDuckGo for several years already just to stop google from taking and selling my info. Weather it truly works or not I dont know but its a great search engine anyway so I figured why not use it.
Your advice to disabling IPv6 protocol in my router settings: I do not see anywhere in my router settings to do this so I googled it, and it looks like there's a way o do this in windows. Is that different that what you're advising? Also I read a windows blog on this and windows 10 says IPv6 is a mandatory part of Windows that they do not advise on disabling. Can you give me some more detail on this, and how to disable it, assuming the windows warning is bull.
Thanks for all of your help.
Private DNS has been around for a little bit on newer devices. However, finding a service that provides both the Private DNS side (TLS) and ad-blocking, filtration of bad domains, etc., has been another whole mess.
I've launched a donation-backed Private DNS service which provides an internet-side option. Think pi-hole style blocking without needing a VPN or only working from your LAN.
What's this entail?
1. Running Android Pie (or anything with the feature ported to it)
2. Using a custom Private DNS Server address that I will provide.
What happens?
1. Your DNS requests are routed via DNS-over-TLS to my CDN virtual machines.
2. Your DNS requests are then locally processed through several internal systems including the infamous Pi-Hole.
3. Final data requests from the local resolver are forwarded via DNS-over-HTTPS to root DNS servers such as 1.1.1.1 and others that are found to support HTTPS protocol.
4. No personal data is stored. Only data with respect to filtration is stored such as blocked versus permitted domains, hit/misses, and caching statistics to continue to develop a more fluid system.
What do I do?
Put "DNS.DEREKGORDON.COM in your Private DNS settings for Android.
Use IP address 35.243.170.151 for other applications to include your home network router, ChromeOS, etc.
Like it? CONSIDER DONATING. This system is kicking out almost one million responses a day for users.
More information is at http://www.derekgordon.com/dns/.
Always provide THANKS no matter what folks. It's the nice thing to do....
So we are looking at a encrypted dns with ad blocking? I would be into trying that.
I'm using dns.agduard.com at the moment on my Huawei P20 pro running Android pie.
Have a number of people using it without issue now....

Cool. Give it a go. My only concern now rests with the attack prevention stuff I've added. It rate limits and bans those who are hitting the server or servers if expanded quite hard. Basically it's to ward off attackers. Anyway no bad reports from it but it's the only factor I'm not totally sure of.
Gonna give it a shot and give you my results in 24hrs.
Cool. I have zero issues on our family's Pixel 2s and 3s. No one said much bad except someone who had login issues on an Xbox when they used the system for their network's DNS. I solved that for them.
Note I'm not filtering Google ads domain as a few people complained since they click the first couple links on Google. I haven't felt intruded upon by ads with this change since making it a couple weeks back.
hi,
sometime i can use this dns, sometime cannot.
my mi 8 using baskalos rom stated coudlnt connect.
issit because of my isp?
Very strange. No one has reported that issue. Is it the same result on WiFi vs mobile data? Want to give me your IP to search logs?
I've used the server in four countries on various WiFi and mobile netwiens without issue on Pixel 3.
How did you get the Private DNS in android Pie to recognize your dns server? I've got my own pi-hole server, yet when I put in my FQDN, I lose internet access on my phone.
First, I don't use Pi-Hole only. I made a custom Debian image and deployed it into the world of CDN. Pi-Hole's opensource software was incorporated as one of my mechanisms for blacklists.
To your point on connection, you need two things: 1) a TLS server to establish the connection and 2) signed certificates for the domain you are using installed on your server. Android will connect via TLS and will verify that your certificate is valid against its root certificates on the device.
Happy note - my server is providing over 250,000 queries daily now and over 90% connect via TLS so that indicates lots of happy Android users.
I'm check yours out and see how well it compares to the VPN connection I currently use to my pihole.
Been loving your Private DNS so far. Great job on it. Question though, do you have a form or something for people to submit domains that are blocked and shouldn't be?
Hey. Feel free to tell me these domains. There is such high usage and hardly any feedback so I haven't even thought about it. I could make a Google Form later.
Actually, I had a spare moment at lunch. Try this: https://forms.gle/oGtAFKAc7yJPmmEZ6

Was gonna request https://go.redirectingat.com be unblocked since many many sites use it to link to products on sites like Walmart and Amazon. Can't use that form though since you require a screenshot URL, and I can't screenshot a redirection site.
You figured out a good workaround to make your request. Processing now, give it a minute and should be good.
All of your requests are cleared if you didn't notice yet. Happy browsing.
Not really sure how to publicize this and it probably isn't worth trying to do... But for those who do use this, and there are plenty of folks, I have been working on some changes.
1. These will not work with Android as I don't have the extra cash to blow on more SSL certificates. But, they will work for home networking purposes:
US.EAST.DNS.DEREKGORDON.COM
US.WEST.DNS.DEREKGORDON.COM
DE.FRUNKFURT.DNS.DEREKGORDON.COM
BR.SAO.DNS.DEREKGORDON.COM
2. DNS.DEREK.GORDON.COM is now a pool of a number of VM instances that are connected to Google's CDN. It will grow as necessary. This helps spread out some of the intensity that has been hitting the TLS daemon.
3. Servers will automatically reboot between once a week to every other week depending on load and latency. Sometimes the intense flood of queries really makes things sluggish. Reboot takes just a few seconds and I'm working for it to time it during off-peak hours so hardly anyone will notice.
Hi, I have my own pihole installed on aws server. Could you please share tutorial how could i make it work with private dns in android pie. Thanks.
A great option for taming the massive onslaught of advertisements constantly invading your phone has been an app available on XDA called AdAway.
Unfortunately, it requires root access, which is not yet available on the Galaxy A71 5G (SM-A716U with Snapdragon 765G).
However, the next best option for managing ads at the device level is using a feature built into Android 9 and up which allows you to set a custom DNS server. And this does not require root access or otherwise hacking your phone. You are just changing a setting.
Many private DNS services exist which provide a variety of additional benefits. Some not only block Ad sites, but also block known malicious sites, and block sites that are not appropriate for children.
This page lists several options for DNS services depending on what you want to block.
https://cyanish.com/how-to-block-ads-and-malicious-domains-in-android-easily/
I find that AdGuard and Nixnet seem to be the most effective at blocking ad sites. OpenDNS and Quad9 are better at blocking malicious or inappropriate sites. I set my home router to use OpenDNS for this reason.
Note that some DNS services may be based in other countries. You may want to do some additional research to help decide which one is most appropriate for you.
Once you have decided which DNS service to try, on your Android phone, go to:
Settings > Connections > More Connections Settings > Private DNS
And enter the host name of the DNS service you want to try.
You may need to reboot your device to see the full change. If you don't get results you are happy with, try a different service and reboot. You can change back to the standard DNS settings at any time.
I use DNS66 and it seems to work well but I haven't tried the others listed above. How do they compare?
I use OpenDNS on my home router since they allow you more control over the types of sites they block.
I tried Quad9. I did not see much ad blocking when using it. But that's not surprising since it is a consortium of companies like IBM, etc. It probably does a nice job blocking malicious sites.
AdGuard worked great at blocking ads. It is a Russian site, and that isn't necessarily a bad thing. But it helps make the point to do your research because whatever service you choose will know the sites you visit (unless you are using the encrypted DNS services specifically for that reason).
Some of the others are probably a better choice if you live in Europe, but in North America there are probably sites that perform better.
I went with Nixnet and have bee happy with it so far.
Ive done well without root using the Paid Adguard version. it worked well on my Huawei mate 10 Pro, and am now using it on the A71 5g AT&T variant.
There is a new version of AdAway on Fdroid
