Thanks Mark,

New problem. Trying to use aes-256-ctr instead. I'm following the syntax in
the dictionary but it throws a red cross on it:

encrypt tData using "aes-256-ctr" with key tMyKey and salt tMySalt

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.
