Re: Change debug encryption on a program?

Exactly.

If so, then "of course" you can "change" it at "compile time" -- just
specify a different value for that parameter. ;-)

Well ... at compile time you SET it ... I'm wondering if there is a way to change it after it's been set.

When you say, "Perhaps via an API?" -- do you mean that when a user
specifies e.g., "DBGENCKEY('Garbage')" you want to change it to some
other value that you control?
No, I'm wondering if there is an API that will decrypt & re-encrypt the debug information on a program setting a new key (obviously providing the original key for decryption purposes).

My object is to be able to change the debug key on delivered product so that suitably powerful users aren't able to guess the key even if they knew it before.
