Creating Valid Fake Signatures

Hey everyone, I'm trying to improve the Nonce Recurrence Attack. I checked out a paper on it, but I wanna take it a step further. I need to figure out how to make some fake signatures that still link to the same public key. I vaguely recall someone mentioning that it's possible to create signatures that can be verified against a key but aren't valid. Anyone know what I mean?

I got what you need, hit me up in PM.

Received your script! Give me a day to check it out and I'll get back to you. Appreciate it. By the way, if anyone wants my Nonce Recurrence Attack script, I’ve got it here. It uses a generator, not the enhanced version. It works fine. I’ll update the code and share the enhanced version tomorrow. Cheers!

Sounds good, man!

Hi guys. Sorry for my English. Can someone share the code for creating signatures? Would really appreciate it. Thanks!
