* [[Pretty Good Privacy|PGP]] is generally considered an example of strong cryptography, with versions running under most popular operating systems and on various hardware platforms. The open source standard for PGP operations is [[OpenPGP]], and [[GnuPG]] is an implementation of that standard from the [[Free Software Foundation|FSF]]. However, the IDEA signature key in classical PGP is only 64 bits long, therefore no longer immune to collision attacks. OpenPGP therefore uses the [[SHA-2]] hash function and AES cryptography.
