digest provides hash function summaries for GNU R objects. The md5,
|
|
sha-1, sha-256 and crc32 hash functions are available. The md5
|
|
algorithm by Ron Rivest is specified in RFC 1321, the SHA-1 and
|
|
SHA-256 algorithm is specified in FIPS-180-1 and FIPS-180-2,
|
|
respectively, and the crc32 algorithm is described in here. For md5,
|
|
sha-1 and sha-256, this packages uses small standalone C
|
|
implementations that were provided by by Christophe Devine. For crc32,
|
|
code from the zlib library is used. For sha-512, a routine by Aaron
|
|
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.
