If none of these options is specified the key is written in plain text. This
means that using the B<rsa> utility to read in an encrypted key with no
encryption option can be used to remove the pass phrase from a key, or by

The B<NET> form is a format compatible with older Netscape servers
and Microsoft IIS .key files, this uses unsalted RC4 for its encryption.
It is not very secure and so should only be used when necessary.
