Subject: SHA-1 cracked?
For IP
Hi Dave,
Bruce Schneier is reporting in his blog that SHA-1 appears to have been
broken by a Chinese group, and that is has collisions "in the the full SHA-1
in 2**69 hash operations, much less than the brute-force attack of 2**80
operations based on the hash length.".
This could have non-trivial implications for many current commercial
operations.
