r-cran-digest 0.6.22-1 (amd64 binary) in ubuntu focal

 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, and spookyhash algorithms) permitting easy
 comparison of R language objects, as well as a function '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.
