434 | RIPEMD-160 is a 160-bit cryptographic hash function. It is intended |
435 | to be used as a secure replacement for the 128-bit hash functions | |
436 | MD4, MD5 and it's predecessor RIPEMD | |
437 | (not to be confused with RIPEMD-128). | |
82798f90 | 438 | |

439 | It's speed is comparable to SHA1 and there are no known attacks |
440 | against RIPEMD-160. | |
