[Question] BF Key

[Speedie123]

Well, Actually I've searched for it but i failed.
Now, when i try to crack exe or whatever, After getting the blowfish key.
I can't put it in cracked exe or something!
I've tried using Notepad++, And I fail using Olly, or Hex etc.
So, If someone got some way about olly or hex about how to do it, I'm asking to share.., Even if there's another way, harder or easier, I want it, But in the right steps, thanks.
