Contributed R Packages

Below is a list of all packages provided by project digest - 'hash' arbitrary R objects.

Important note for package binaries: R-Forge provides these binaries only for the most recent version of R, but not for older versions. In order to successfully install the packages provided on R-Forge, you have to switch to the most recent version of R or, alternatively, use the package sources (.tar.gz) in older versions of R. All packages are built/checked according to this schedule.

  digest - 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, sha-256 and crc32 algorithms permitting easy comparison of R language objects. 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 and sha-256, this packages uses small standalone implementations that were provided by Christophe Devine. For crc32, code from the zlib library 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.
