The digest package provides a function 'digest()' for the creation
|
|
of hash digests of arbitrary R objects (using the md5, sha-1, sha-256
|
|
and crc32 algorithms) permitting easy comparison of R language
|
|
objects, as well as a function 'hmac()' to create hash-based message
|
|
authentication code. The md5 algorithm by Ron Rivest is specified
|
|
in RFC 1321, the sha-1 and sha-256 algorithms are specified in
|
|
FIPS-180-1 and FIPS-180-2, and the crc32 algorithm is described in
|
|
ftp://ftp.rocksoft.com/cliens/rocksoft/papers/crc_v3.txt. For md5,
|
|
sha-1, sha-256 and aes, this package uses a small standalone
|
|
implementations that were provided by Christophe Devine. For crc32,
|
|
code from the zlib library is used. For sha-512, an implementation
|
|
by Aaron D. 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.
