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 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. For + xxhash, the implementation by Yann Collet is used. For murmurhash, an + implementation by Shane Day 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.""" + + homepage = "http://dirk.eddelbuettel.com/code/digest.html" + url = "https://cran.r-project.org/src/contrib/digest_0.6.9.tar.gz" + list_url = "https://cran.r-project.org/src/contrib/Archive/digest" + + version('0.6.9', '48048ce6c466bdb124716e45ba4a0e83') + + extends('R') + + def install(self, spec, prefix): + R('CMD', 'INSTALL', '--library={0}'.format(self.module.r_lib_dir), + self.stage.source_path) |
