以下轉載自 SHA-1 Broken
SHA-1 has been broken. Not a reduced-round version. Not a simplified version. The real thing.
* 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.
* collisions in SHA-0 in 2**39 operations.
* collisions in 58-round SHA-1 in 2**33 operations.
