Wei Dai's crypto++ has pretty much everything, in c++. <http://www.eskimo.com/~weidai> has the info and a pointer to the latest version (2.0) at an export-controlled-site. The old versions, (1.0 still has the algorithms RSADSI disputed) are available in <ftp://ftp.utopia.kacktic.nl/pub/replay/pub/crypto/LIBS> under the names crypto10.zip and crypto11.zip (I think). I didn't see 2.0 . I think Hal Finney's has some of it ported to Java. ( www.portal.com is inaccessible at the moment)
