title: C++ RSA Signing
body: <p>I am trying to sign some data with given RSA parameters.</p>
  
  <p>I am given Modulus, Exponent, D, DP, DQ, P, Q, and InverseQ. What library or methods would be the easiest and simplest to use to compute this signature. In C#, they have a specific method for signing data once you give parameters. Again, I am looking for simplicity and possibly just a straight up header and cpp file if possible. Thanks.</p>
