WebMay 10, 2024 · Data encryption is to convert plaintext data into ciphertext through a data encryption algorithm and then transmit the ciphertext. After the recipient receives the ciphertext, the ciphertext is restored to plaintext, which provides protection and technical support for information security.

Also, in ECB and CBC modes, we should use a padding algorithm like PKCS 5. So the size of data after encryption is: ciphertext_size (bytes) = cleartext_size + (16 - (cleartext_size % 16)) For storing IV with ciphertext, we need to add 16 more bytes. 4. …
