In the context of this library, bytes can be represented as
lists of integers between 0 and 255. Such lists can be converted to and
from
hexadecimal notation with the following bidirectional relation:
- [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].

which is often used to transfer or embed binary data in applications.
