The random number generator must be seeded prior to calling
RSA_padding_add_xxx().
+If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to
+external circumstances (see L<RAND(7)>), the operation will fail.
RSA_padding_check_xxx() verifies that the B<fl> bytes at B<f> contain
a valid encoding for a B<rsa_len> byte RSA key in the respective
recovered data, -1 on error. Error codes can be obtained by calling
L<ERR_get_error(3)>.
