Hi Vitaly,

Thank you for the detailed explanation.

strtoul() supports prefixing the ascii-hex string with "0x".  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
