Has anyone stopped using MD5 for hashing evidence files since the disclosure of collision issues at the Crypto 2004 conference?
The current discussion apart, it's interesting to note that Ferguson & Schneier (Practical Cryptography, 2003) recommend that neither MD5 nor SHA-1 be used. The authors set a 'security target' of 128 bits strength for their recommendations: SHA-256 is the 'weakest' hash function they recommend.
