(synopsis "Create cryptographic hash digests of R objects")
(description
"This package contains an implementation of a function 'digest()' for the
creation of hash digests of arbitrary R objects (using the md5, sha-1,
sha-256, crc32, xxhash and murmurhash 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.")
