Incorrect aes key length 13 bytes
WebDec 2, 2016 · One reason to not directly use bytes as key is that hardware devices (HSM's, smart cards) may not even expose the bytes to the software in the first place. In that case the error may be thrown in advance, depending on the implementation.

If you have a different size input use some kind of KDF to transform it to the correct length. If that input is a password this step is even more important. You should a key strengthening construction, such as PBKDF2 with sufficient iterations and a salt.
