Create cryptographic hash digests of R objects
Description
The digest package provides functions for the creation of
`hash' digests of arbitrary R objects using the md5, sha-1 and
crc32 algorithms permitting easy comparison of R language objects.
The md5 algorithm by Ron Rivest is specified in RFC 1321, the SHA-1
algorithm is specified in FIPS-180-1 and the crc32 algorithm is
described in ftp://ftp.rocksoft.com/cliens/rocksoft/papers/crc_v3.txt.
For md5 and sha-1, this packages uses two small standalone C
implementations that were provided by by Christophe Devine. For
crc32, code from the zlib library is used.
.
Please note that this package is not meant to be used for
cryptographic purposes for which more comprehensive (and widely
tested) libraries such as OpenSSL should be used.
