"""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."""
