WebOct 19, 2024 · TLS handles padding for block size. You should be able to pad with zeros if you want as long as the input is a multiple of 16 bytes. The resulting output will be the same length as the input. The decrypted text on the other side will have the padding and be a multiple of the block size. Most padding scheme use a length and known pad character. WebIn my application I am encrypting and decrypting data using secretKey. For that I am using AES algorithm.
