digest: Create cryptographic hash digests of R objects
The digest package provides a function 'digest()' for the
creation of hash digests of arbitrary R objects (using the md5, sha-1,
sha-256 and crc32 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 a 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.
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.
