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.
