AES

  • 建议 Key 至少 256
  • CBC/CTR/GCM/CCM/EAX
  • 不要使用 ECB
  • used by
    • US Government to protect their own files - FIPS 197

Block cipher mode

ECB should not be used if encrypting more than one block of data with the same key.

CBC, OFB and CFB are similar, however OFB/CFB is better because you only need encryption and not decryption, which can save code space.
