[BSD] MD5 R.I.P

[Hajdú Zoltán]

On 2004. 08. 25., Marton Fabo has wisely spoken:

főleg a vége a lényeg, a "So what's the big news?"

Some very bright researchers in China presented a paper, Collisions
for Hash Functions MD4, MD5, HAVAL-128 and RIPEMD, at the Crypto 2004
conference in August 2004, and it's shaken up the security world
considerably. This was some outstanding cryptography research.

They have found ways to reliably generate collisions in four hash
functions much faster than brute-force time, and in one case (MD4,
which is admittedly obsolete), with a hand calculation. This has been
a stunning development.
