Package

r-digest

Description

Create Compact Hash Digests of R Objects. 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.
