WebFeb 9, 2024 · The AES Encryption algorithm (also known as the Rijndael algorithm) is a symmetric block cipher algorithm with a block/chunk size of 128 bits. It converts these individual blocks using keys of 128, 192, and 256 bits. Once it encrypts these blocks, it joins them together to form the ciphertext.

WebMar 7, 2024 · Encryption is a process which transforms the original information into an unrecognizable form. Decryption is a process of converting encoded/encrypted data in a form that is readable and understood by a human or a computer.
