Data Encryption Standard (DES)

Advanced Encryption Standard (AES)


  • Symmetric Key. AES, Triple-DES, Escrowed Encryption Standard.
  • Asymmetric Key. DSA, RSA, ECDSA.
  • Hash Standards. SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256.
  • Random number generators. See annex c.
  • Message authentication. CCM, GCM, GMAC, CMAC, HMAC.
