I should like to announce a new version of the Haskell Cryptography Library. Version 3.0.3 supports: • DES • Blowfish • AES • Cipher Block Chaining (CBC) • PKCS#5 and nulls padding • SHA-1 • MD5 • RSA • OAEP-based encryption (Bellare-Rogaway) • PKCS#1v1.5 signature scheme • ASN.1 • PKCS#8 • X.509 Identity Certificates • X.509 Attribute Certificates It also includes Base64, a hexdump function, support for Word128, Word192, Word256 (key sizes for AES) and beyond. The ASN.1 handling has been re-written. Details on how to use it are contained in the user guide http://www.haskell.org/crypto/ReadMe.pdf. Haddock documentation is available at http://www.haskell.org/crypto/doc/html. See the home page (http://www.haskell.org/crypto) for downloading. Dominic.
