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.
