# License

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

This library is offered under the **BSD** license and includes several derivative works from Java, C and JavaScript sources.
