I hope I'm posting in the right place...
I'm searching for a reliable Android App that can grab the MD5 of a file (apk, zip, etc...) and save it to a file.
I attached an MD5 file as an example. That is an MD5 file i had manually created.
I also had added the .txt to the end so I could upload it.
Thanks a bunch!
***EDIT/UPDATE: I've found an older tool for generating the MD5 file and updated it (for better compatibility). I now have a workaround for this small, yet important, hurdle. Thank you!

What is it? i read somewhere that if a radio and checksum don't match, it has a negative effect.
its pretty simple. its just a set of numbers and letters, if they match up perfectly with the one in the op of the radio or rom then your good to go. If they dont match you run the risk of bricking your phone. http://forum.xda-developers.com/showthread.php?t=706705

Download it again and check. No way to fix it if it's corrupt, i.e. MD5 sums don't match.
MD5 is a mathematical algorithm, used in encryption and other security applications.
When you run MD5 software on a file it performs the calculation and out comes a long hexedecimal number which is refered to as the MD5 checksum.
It's customary for this checksum to be posted along with the link to files such as ROMs and radios.
When you download, you can then run your own MD5 software on the downloaded file. It will perform the exact same mathematical calculation and give you the MD5 checksum of the file you have downloaded.
If your checksum matches the one posted by the dev, you can be sure you have an accurate copy of the downloaded file. If they don't match, then your download is either corrupt, or possibly some kind of trojan.
You should never install any software if the MD5 sum does not match the one provided by the dev. Instead, try downloading the file again, perhaps from a different mirror. If all else fails, contact the dev as it's possible they might have posted an incorrect checksum, or may have an alternate means by which you can obtain the file.

how do you verify if they match or not?

use any file manager you have and navigate to the zip file
tap and hold on it and select properties
somewhere it will say show md5 checksum or calculate md5 checksum
you will see a row of numbers and letters
then check it if it is the same withe one from the download link
Hello,
I'm trying to modify a couple of roms to remove some APKs and add anothers, (Supercharged and Lithium) but I keep getting md5 mismatch, even though I modified the MD5 files with the new MD5 values (using md5sums for windows)
Can you tell me what am I doing wrong / how to force CWM Recovery to ignore the MD5 files?
Thanks
The easiest thing to do is to bypass md5sum checks by leaving the md5 file empty.

It didn't work with an empty file, neither did it without an md5 file

I've had problems with if having bad checks even with an empty md5 file. formatting my sdcard fixed it. Just backup your stuff first. hopefully yo don't have 28 GB of music like me
Here is a MD5 checker for windows machines. It calculates the MD5 then displays a form with two buttons, you can either paste a MD5 into the text box and then check the calculated MD5 with the entered MD5 to see if they match.
Or after calculating the MD5 you can simply get the MD5 of the file you selected. Its very easy to use.
Find your file in windows explorer, right click on the file, and then select "Send To" and choose MD5 Checker and thats it

The MD5 of the attachments in this post.....if the person is downloading your app (unless they did as I have just done - I have an MD5 checker already) would suggest that they don't have an MD5 app already so the numbers you have posted seen pointless to the end user. They would have to install your app to check the integrity of the file they just downloaded.....and the purpose of providing the MD5 number is to check the download for either corruption and/or misformation caused by malware insertion etc.
Some constructive feedback. The installer looks nice and professional.
The app....how does it work? I have been using MD5 check and SHA1 and SHA2 checking for quite sometime now (so I know what I am talking about). I have mine setup through right click context menus.
Do you select the app in explorer with your app open and then go generate MD5??? No instructions?
Your uninstall method is messy and lefts junk/fragments etc in on the drive. The directory remain as well as the uninstall executable.

Uninstall isn't even mine. It's auto created by the packaging tool I'm using.
I kind of also have left this to the side as it doesn't seem popular.
And I don't know what you mean by saying posting the md5s of my tool is pointless. It's just a reference for people to familiarize themselves with md5 hash keys.
And all you do is select the file you want to check and right click it then select "send to" then "md5 checker" and it will generate the hash key then enable the interface.
Again I pretty much quit this. Nobody's interested.

one star for the sig whats up with that post in that forum? that angry person is crazy lol. Does he own the servers that run xda? i Mean is he the boss? Can't be. I dunno I gotta find out what thats about though its going drive me crazy if i don't pm me even pleasee lol
I know you said you pretty much quit this, but I just discovered it, and I am interested in getting it working as described in the OP.
I installed your program & set up the sendto, but the MD5 Checker.exe GUI front end for md5sum.exe isn't working. "Get MD5" doesn't do anything, and "Check MD5" always returns a mismatch.
Is this incompatible with Win7 x64, or have I screwed something up installing it?
Thanks.
When I sold tech I hated the instructions that assumed a body of knowledge when I was setting up labs that I didn't have. I have, hopefully in a clear fashion, explained exactly how to check MD5 sum's using ES File Explorer. I had no body of knowledge in this either so maybe my experience can save you some time. The MD5 Sum check is essentially comparing "serial numbers" to make sure that the download is as labeled. The problem with precise directions is everything changes. The biggest issue is to remember that we need to compare the MD5 sums and that somewhere, after a long press on the file we have downloaded and is on our phone, ES File Explorer will generate a MD5 sum.
To check the MD5 sum of a zip file you downloaded and will reside on your phone, begin by copying (cut and pasting) the MD5 sum number from the download page when you download the ROM, update, or the Radio, etc. You will use this number to compare to the MD5 sum generated by ES File Explorer. Once you have that number written down (cut and pasted), open ES File Explorer, navigate to the zip file on your phone that you downloaded and long press the zip file whose MD5 sum you need to verify before flashing. Then choose properties in the ES File Explorer window- it’s all the way at the end- for the zip file whose MD5 sum you are checking. When you do long click the zip file in ES File Explorer a window will appear and in the lower left hand corner of the ES File window. It says “show check sum”, click it. In the next window choose MD5 and then choose calculate. ES file Explorer will generate the file’s MD5 Sum. This sum and the MD5 sum you wrote down from the original download page should match. If they do not, do not flash it. Find where there is a downloadable that has a matching MD5 sum.

This works the same in pretty much every file browser I've ever used on Android. You don't really need to copy it though, all you need to remember is the last 5 digits, if they are the same, the rest will be as well. Or you can just task switch from the browser to the file explorer to verify. At least that's how I do it.
Es is great but lately Ive been using "Solid Explorer". When you ask for the md5 it comes back with the md5 and a spot to paste the one you copied from the dl site. It compares them and gives you a "check mark" if they match.
Hi, I recently published my first android application on Google Play.
It's a tool to help you verify that the files on your device are not corrupted (incomplete download, ...).
It can be used to:
- verify a file tagged with a CRC32 checksum in the file name (My_Video_[89AF8C3D].avi).
- verify files with a .sfv file. The .sfv file contains a list a files and their CRC32 checksums.
- verify files with a .md5 file. This .md5 file can contains a list a files and their MD5 checksum or only the MD5 checksum (it will verify the file with the same name without the .md5 extension).
- verify files with a .sha1 file.
- verify a .tar.md5 file. It will find the md5 checksum at the end of the file to verify the tar part.

Please check out the app and let me know if you have any problems, questions, suggestions.
Thanks
A new version is available that can generate a sfv/md5/sha1 file from the selected files.
Thank you sir, exactly what i've been looking for ;]
What an excellent app, thanks a lot !

This was EXACTLY what I was looking for. It does what it supposed to do, check the SFV file on Android.
I dont know why this is not in Google Play, I had to download it from your site.
One side note, when I quick the app, it hangs, "Unfortunately, FilesChecker has stopped" error, with the lastest version from your site, v1.5.4.
EDIT
And I couldnt run it on my S5301 with android 4.0.4.
Probably because it has low resolution?
great app, thank you!
Is there any way to get the app to read from an SD Card?
