AES

• [[Symmetrical Encryption Algorithm]]

• [[Block Cipher]]

• welp idk how it works (yet) but

• openssl aes-256

2 modes

• ECB

  • based on key length, break plaintext into chunks, so [128]-[128]...

  • same message will give same result, insecure

  • does not encrypt message well, some data still visible

  • attacker could swap portions that are known to be like date sent and screw up data

• CBC
