The type of a reveal hash.

The hashing schemes supported by the reveal hash.

A Map module for storing reveal-hash-indexed values.

size ~scheme returns the size of reveal hashes using the scheme specified in input.

zero ~scheme returns the reveal hash corresponding to the zero hash for the scheme specified in input.

Formatting function for reveal-hashes.

equal hash1 hash2 checks if the two reveal-hashes hash1 and hash2 are equal. This function must preserve the equality of individual supported hashing schemes. If hash1 and hash2 are hashes obtained from the same supported hashing scheme, then the equal function from that hashing scheme is used to determine whether they are equivalent. Otherwise, they are different.

compare hash1 hash2 compares the values of the reveal hashes hash1 and hash2. This function must preserve the ordering of individual supported hashing scheme. If hash1 and hash2 are reveal-hashes obtained from the same hashing scheme, then compare hash1 hash2 should return the same result of the compare function exposed by the hash module corresponding to their hashing scheme.

The encoding of reveal hashes.

hash_string ~scheme ?key strings hashes strings using the supported hashing scheme given in input.

hash_bytes ~scheme ?key strings hashes bytes using the supported hashing scheme given in input.

scheme_of_hash hash returns the supported hashing scheme that was used to obtain hash.
