Free & Portable Checksum Tools

#1 Post by I am Baas » Wed Jun 16, 2010 3:05 am

1. Chaos MD5 (available in a unicode & non-unicode versions)
Chaos MD5 is a free MD5 generator for Windows. Input or drag-and-drop any file into this free program and it will generate a MD5 checksum for that file. That simply means it generates a unique signature for each and every file. Chaos MD5 is able to generate the MD5 hash for a string of text also. That is a very handy tool for anyone to create a password hash.
2. FileVerifier++
FileVerifier++ is a Win32 application for verifying the integrity of files. FileVerifier supports various algorithms by means of dynamically loadable hash libraries.
Download the zip package @ http://www.programmingunlimited.net/sit ... v#download

3. MD5 Checksum Tool
MD5 ChecksumTool is an application designed to allows users to generate the file checksum (MD5 Hash) of any file or string. It can also be useful to check if an executable file is legit. It is possible to scan all files of a folder with subfolders selectable (Recursive) and create a report with file checksum (MD5) of all files with filename and file size. Other features are to compare a file with an MD5 hash and compare two files with file checksum.

Very easy to use with drag & drop of files and folders.

Tested out MD5 Checksum Tool. Nice program that combines the features of a lot of smaller hash programs including a recursive checksum creator, but no recursive checksum verifier. You can't use it to check an entire folder for changes or corruption.

@I am Baas - why you not considered adding these to TPFC? MD5 Checksum Tool is a very competitive MD5 checksum tool!

Bumping for relevance, I'm posting here a good related write-up I came across recently:
Some related forum topics (feel free to add your own):
Last but not least, there is also this "Intro to file posting accessories" by our dear mod (viewtopic.php?p=81776)...

Two of the smallest footprint, yet quite decent hash checkers:

PocketHash v1.03 (48kb)
Rob Keir's Hash v1.04 (28kb)

Nice.

A few notes on the link you posted:

1. That article seems like more of an argument for Multipar rather than checksum tools. If files on your machine are corrupting by just a bit or two, it's better to have data redundancy rather than data verification. While I like the idea of file verification running and being notified if something's amiss, I do think daily checks are unnecessary and maybe wasteful. Once a week or once a month seems a lot more worthwile.

2. Did I miss where the script he built is located? It didn't seem like he published it.

Kudos seeing someone putting hashing and verification into a system that's actively solving problems.

On a related note, I feel like this deserves it's own thread. Should I push it?
