=head1 DESCRIPTION
B<dummy> is ignored.
-The random number generator must be seeded prior to calling RSA_sign_ASN1_OCTET_STRING().
+The random number generator must be seeded when calling
+RSA_sign_ASN1_OCTET_STRING().
+If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to
+external circumstances (see L<RAND(7)>), the operation will fail.
RSA_verify_ASN1_OCTET_STRING() verifies that the signature B<sigbuf>
of size B<siglen> is the DER representation of a given octet string
