Someone provide me an RSA public key from a CA certificate.
I will flip a single bit in the modulus, then sign a message with the corresponding private key.

  @dakkar So, the thing is, I got the idea for this trick while reading a post titled "Tony Hawk's Pro Strcpy".
  Long ago the Xbox Linux hackers had an stack where they modified four bytes of a key, and I thought to myself, "amateurs, I can do that in 1 bit".
