WebJun 3, 2024 · The IV is sent separately as a short message using ECB Mode. Then, CBC applies the encryption algorithm to the block, creating the first block of ciphertext. CBC then XORs this block with the second plaintext block and the applies the encryption algorithm to produce the second ciphertext block, and so on until the end of the message. WebECB should not be used outside of very specific circumstances. Random Padding¶ For RSA, it is essential to enable Random Padding. Random Padding is also known as OAEP or Optimal Asymmetric Encryption Padding. This class of defense protects against Known Plain Text Attacks by adding randomness at the beginning of the payload.
