[det]hex_bytes(?Hex, ?List)

Relation between a hexadecimal sequence and a list of bytes. Hex is an atom, string, list of characters or list of codes in hexadecimal encoding. This is the format that is used by crypto_data_hash/3 and related predicates to represent hashes. Bytes is a list of integers between 0 and 255 that represent the sequence as a list of bytes. At least one of the arguments must be instantiated. When converting List to Hex, an atom is used to represent the sequence of hexadecimal digits.

Example:

?- hex_bytes('501ACE', Bs).
Bs = [80, 26, 206].
