signing using RSA public key algorithm
<p>I am planning to use php for generating serial number for my software which is written using MSVC++. The method i am optiong is hashing the information and sign it using Private key. In MSVC++ i am able to verify a hash signed by RSA public key algorithm using native API's. Is it possible to sign a hash using RSA public key algorithm in php.</p>

<p>Please advice.</p>

<p>Regards,
John. </p>
