size of the digest

digest msg hashes msg to generate a size bytes long digest

For hashes that offer an incremental interface, the internal state of the algorithm is kept in an object of type state which is initialised using init and needs to be stored and passed as an argument to the other functions in the interface. It is automatically freed when no longer required.

init () initializes and returns an internal state of the hash algorithm

update st msg updates the internal state of the hash algorithm st with buffer msg.

finish st generates and returns a digest, without invalidating the state, meaning that further calls to update can be made
