I don't know what software to use

[BirdDad]

That stuff is way over my head.
All that I am trying to do is :
the password starts with don'tCumKnocking1010
then it is two characters which I do not know, I need to test for all of them
then the password ends with :
5050HaGotYa%
so it if the two characters are AB then :
don'tCumKnocking1010AB5050HaGotYa%
would be the complete password.
Is there an easy way to do this?
Thank you
