I can see this. The problem is that licdata is never assigned any value. You use licdata[0], licdata[1], ... licdata[14] in your code, but the array doesn't contain anything, it is just completely empty.

You also use actcode := in your code, but actcode is no variable parameter. You overwrite it before evaluating the value which was passed to the procedure.

I don't know this...the code for RC6 is not mine it is from DCPCrypt2...I am only passing him a string to be decrypted...I believe DCPCrypt code handles the whole job.

Neither DCPcrypt nor DCPcrypt2 have a function called RC6Decrypt. They just have a RC6 class containing a procedure called DecryptECB which decrypts exactly one block, nothing more or less. You must be using some wrapper for DCPcrypt.

It also looks much like you're using FGInt and some prankster renamed it to BIGInt. (refactoring )
