=head1 NAME
-RSA_generate_key - Generate RSA key pair
+RSA_generate_key - generate RSA key pair
=head1 SYNOPSIS
The modulus size will be B<num> bits, and the public exponent will be
B<e>. Key sizes with B<num> E<lt> 1024 should be considered insecure.
-The exponent is an odd number, typically 3 or 65535.
+The exponent is an odd number, typically 3, 17 or 65537.
A callback function may be used to provide feedback about the
progress of the key generation. If B<callback> is not B<NULL>, it
