## Create cryptographic hash digests of R objects

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.
