b6d44341 AB |
432 | RIPEMD-160 is a 160-bit cryptographic hash function. It is intended |
433 | to be used as a secure replacement for the 128-bit hash functions | |
434 | MD4, MD5 and it's predecessor RIPEMD | |
435 | (not to be confused with RIPEMD-128). | |
82798f90 | 436 | |
b6d44341 AB |
437 | It's speed is comparable to SHA1 and there are no known attacks |
438 | against RIPEMD-160. | |
