handle

       With this function, the caller sets the key for subsequent cipher operations.

       The key must be in DER format as follows

       SEQUENCE { n INTEGER ({ rsa_get_n }), e INTEGER ({ rsa_get_e }) }

       After the caller provided the key, the caller may securely destroy the key as it is now maintained by the
       kernel.

       return upon success the value of the maximum size for the asymmetric operation is returned (e.g. the
       modulus size); a negative errno-style error code if an error occurred
