RIPEMD (RIPE Message Digest) is a collection of cryptographic hash functions that was developed in two stages: the original RIPEMD in 1992 and additional variants in 1996. The RIPEMD family encompasses five functions: RIPEMD, RIPEMD-128, RIPEMD-160, RIPEMD-256, and RIPEMD-320, with RIPEMD-160 being the most commonly used.

The original RIPEMD and RIPEMD-128 are not regarded as secure due to their 128-bit output being considered too small and, in the case of the original RIPEMD, due to inherent design weaknesses. The 256-bit and 320-bit versions of RIPEMD offer the same level of security as RIPEMD-128 and RIPEMD-160, respectively. These variants are specifically designed for applications where a longer hash output is necessary while maintaining adequate security.

Although not as widely adopted as SHA-1 and SHA-2, RIPEMD functions are used in various contexts, including Bitcoin and other cryptocurrencies based on the Bitcoin framework.
