Hi Vitaly, Thank you for the detailed explanation.

To differentiate between a keyid and pathname, why not require the keyid be prefixed with "0x", as opposed to requiring the pathname to be prefixed with '@', like "--keyid @/path/to/cert.pem". The new test would be "OPTS=--keyid=0xaabbccdd" thanks, Mimi
