Hash: SHA1

Hi,
Bruce Schneier anounced in the latest CRYPTOGRM, September 15, 2004
that:


" At the CRYPTO conference in Santa Barbara, CA, last month,
researchers
announced several weaknesses in common hash functions.

- --- snipped __

this year, Eli Biham and Rafi
Chen, and separately Antoine Joux, announced some pretty impressive
cryptographic results against MD5 and SHA.  Collisions have been
demonstrated in SHA.  And there are rumors, unconfirmed at this
writing, of results against SHA-1."

He advices people to use the longer SHA-hashes until a new better hash
is invented. He suggests a HASH-contest like the AES-process to get a
new hash.
