%description
Implementation of a function 'digest()' for the creation of hash digests
of arbitrary R objects (using the 'md5', 'sha-1', 'sha-256', 'crc32',
'xxhash', 'murmurhash', 'spookyhash', 'blake3', 'crc32c', 'xxh3_64', and
'xxh3_128' algorithms) permitting easy comparison of R language objects,
as well as functions such as'hmac()' to create hash-based message
authentication code. Please note that this package is not meant to be
deployed for cryptographic purposes for which more comprehensive (and
widely tested) libraries such as 'OpenSSL' should be used.
