WebThe key is hexadecimal. So every two characters makes up one hexadecimal byte, which brings the length down to 32 actual bytes. There are 8 bits per bytes, so 8*32 = 256. Addition, for additional clarity: each of the 64 hexadecimal character encodes 4 bits. 64×4=256 bits, the key size. WebEncryption keys for AES are not expressed in characters or letters. Encryption keys are a series of 128 (or 256) bits. If you are using some kind of interface to enter a text-based password, internally it is turning your typed password into bits. It may be using a complex routine like PBKDF2, or a single iteration of SHA-1.
