Download As3 Crypto Framework

As3 Crypto is a cryptography library written in Actionscript 3 that provides several common algorithms. This version also introduces a TLS engine (TLS is commonly known as SSL.)

* Protocols: TLS 1.0 support (partial)
* Certificates: X.509 Certificate parsing and validation, built-in Root CAs.
* Public Key Encryption: RSA (encrypt/decrypt, sign/verify)
* Secret Key Encryption: AES, DES, 3DES, BlowFish, XTEA, RC4
* Confidentiality Modes: ECB, CBC, CFB, CFB8, OFB, CTR
* Hashing Algorithms: MD2, MD5, SHA-1, SHA-224, SHA-256
* Paddings available: PKCS#5, PKCS#1 type 1 and 2
* Other Useful Stuff: HMAC, Random, TLS-PRF, some ASN-1/DER parsing

You can look at a demo of the functionality of the library. It's built with Flex 2. It includes a unit test tab, and a Benchmark tab.

This is what the benchmark tab outputs on my computer (Athlon64 2Ghz):
