Title: Create Compact Hash Digests of R Objects
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 and murmurhash algorithms) permitting easy comparison of R
language objects, as well as a function 'hmac()' to create hash-based
message authentication code.
.
The md5 algorithm by Ron Rivest is specified in RFC 1321, the sha-1
and sha-256 algorithms are specified in FIPS-180-1 and FIPS-180-2,
and the crc32 algorithm is described in
ftp://ftp.rocksoft.com/cliens/rocksoft/papers/crc_v3.txt.
.
For md5, sha-1, sha-256 and aes, this package uses small standalone
implementations that were provided by Christophe Devine. For crc32, code
from the zlib library is used. For sha-512, an implementation by Aaron
D. Gifford is used. For xxhash, the implementation by Yann Collet is used.
For murmurhash, an implementation by Shane Day is used.
.
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.
