Cleartext vs ciphertext

WebNov 14, 2024 · The AES doesn't change the size, and the ciphertext size is equal to the cleartext size. 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. … WebAug 2, 2024 · Ciphertext, or encrypted text, is a series of randomized letters and numbers which humans cannot make any sense of. An encryption algorithm takes in a plaintext message, runs the algorithm on the plaintext, and produces a ciphertext. ... The terms cleartext and plaintext are sometimes confused.
