Documentation

A message-digest is a function taking some input and returning a fixed-length hash. The Message Digest suite of CHICKEN eggs provides support for a separation of digest algorithm and message source.

Eggs, such as sha2, provide one or more sha...-primitive modules; many have bit-length variants. The primitive modules package the algorithm and the message-digest-utils module packages the message source support. The message-digest-type module supports efficient re-use of the same primitive with many different sources.

Please consult the documentation of the eggs in the Requirements section for usage information and examples.
