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
