Sample Programs RSA Encryption Scheme (OAEP and SHA) The following code demonstrates RSA encryption using OAEP. curl. OpenSSL Unicode C The PKCS #1 standard defines the mathematical definitions and properties that RSA public and private keys must have. Lets consider really small numbers for a moment.
