The problem is surely with the length of the key, I have tried different length but I am getting the same, could you please tell me the length of the key please, I am new to cryptography, I have made some research but still can't figure out the problem. Thanks a lot for your answers.
AES supports 128, 192 and 256 bit keys, so the number of bytes needs to be 16, 24, or 32. Note that the latter two may not be available in all circumstances (as the comment in the "kgen.init(128)" line mentions).
