Since this article, I won’t post the language reference of such libraries as before. It’s really a boring thing to do repeated works. All the language reference you will find in the packaged file provided on the corelib project home http://code.google.com/p/as3corelib/ , or download from this link http://as3corelib.googlecode.com/files/as3corelib-.92.1.zip directly.

Thanks!

Package Crypto:

All the common crypto algorithms are packaged together here. It includes algorithms MD5, SHA1, SHA224, SHA256 and a special WSSEUsernameToken for Web Services Security. Take it easy, there is little to learn to take advantage of these stuffs. Just follow me!
