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. WebSep 17, 2024 · The most used symmetric cryptography algorithm today is AES (Advanced Encryption Standard). AES is a cipher block system able to use 128, 192 and 256 key length where that key operates over blocks of 128 bits of plain text to generate 128 bits of encrypted text. AES is used pretty much everywhere.
