I think you can either specify a key, or a password with an optional 
salt.

If you specify a password it uses the provided salt (or a random one if 
one is not provided) to generate a key of the correct length (the bit 
length of the cipher).

If you provide a key then it uses that verbatim to encrypt the data (in 
this case the key must be the correct number of bits as defined by the 
chosen cipher - 256 in this case).

Warmest Regards,

Mark.
