The digest package provides two functions for the creation of
`hash' digests of arbitrary R objects using the md5 and sha-1
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. This packages uses two small
standalone C implementations (that were provided by by Christophe
Devine) of the md5 and sha-1 algorithms.
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.

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.
