MD5 is dead !

[drongo]

We announce two different Win32 executable files with different functionality but identical MD5 hash values. This shows that trust in MD5 as a tool for verifying software integrity, and as a hash function used in code signing, has become questionable.

Let this not discourage you. To calculate much stronger hashes than the outdated MD5, you can use HashCalc (http://www.slavasoft.com/zip/hashcalc.zip). It's free and supports MD2, MD4, MD5, SHA-1, SHA-2 (256, 384, 512), RIPEMD-160, PANAMA, TIGER, ADLER32, CRC32. It can work with files up to 15 GB. It works with all possible extensions.

Do you feel the same on SHA-1?

I long have made and still do make use of Integrity Checker app that originated in Win98 era and depend on it for reporting equal/unequal changes or matches when scanning files of many sorts.
