What is the difference between key size and block size (for AES)?

WebAES has a fixed block size of 16 bytes regardless of key size. Assuming you use PKCS 5/7 padding, use this formula: cipherLen = clearLen + 16 - (clearLen mod 16) Please note that if the clear-text is a multiple of the block size then a whole new block is needed for padding.

WebFor example, a single invocation of the AES algorithm transforms a 128-bit plaintext block into a ciphertext block of 128 bits in size. The key, which is given as one input to the cipher, defines the mapping between plaintext and ciphertext.

WebAES is a block cipher, which is an encryption algorithm that uses a secret key to transform a plaintext into a ciphertext of the same size (referred to as the . block size). Currently, AES is one of only two block cipher standards that are approved by NIST. The other block cipher standard is the Triple Data Encryption Algorithm (TDEA) [4]
