crypto_rsa_exptmod - RSA modular exponentiation : Input data : Input data length : Buffer for output data : Maximum size of the output buffer and used size on success : RSA key : 1 = Use RSA private key, 0 = Use RSA public key Returns: 0 on success, -1 on failure

)

crypto_rsa_free - Free RSA key : RSA key to be freed

This function frees an RSA key imported with either crypto_rsa_import_public_key() or crypto_rsa_import_private_key().
