The following tables compare general and technical information for a number of cryptographic hash functions. Please see the individual functions' articles for further information. This article is not all-inclusive or necessarily up-to-date.
General information
Basic general information about the cryptographic hash functions: year, designer, references, etc. The column "Year" refers to the first official description of the algorithm, not designed date.

Notes
- ^ The omitted multiplicands are word sizes.
- ^ Some authors interchange passes and rounds.
- ^ The size of message digest equals to the size of chaining values usually. In truncated versions of certain cryptographic hash functions such as SHA-384, the former is less than the latter.
- ^ The size of chaining values equals to the size of computation values usually. In certain cryptographic hash functions such as RIPEMD-160, the former is less than the latter because RIPEMD-160 use two sets of parallel computaion values and then combine into a single set of chaining values.
- ^ The maximum input size=2^length size-1. For example, the maximum input size of SHA-1=2^64-1=16Eib-1Eib.
