Datastage parameter encryption

[ogmios]

Did anyone already fully "crack" the 2-way encryption algorithm used in "Encrypted" parameters?

At first sight the encryption looks pretty weak, but I haven't been able to figure out the full algorithm. So far:

* every character gets encrypted to 3 characters
* the third character is one out of 8 characters per parameter position (e.g. for the first position in the parameter 1 character of "98;:IHKJ" and they keep repeating in the same order);
* the second character is changed per block of 8 characters.

[wrote myself a function to decrypt the parameters in the meantime]

Just for fun,
