Subject: openssl certificate fingerprint

Sorry folks,

this should be a FAQ but I googled with no useful results. The standard
library OpenSSL RDoc is very poor.

I just need the Ruby equivalent of this command line:

openssl x509 -noout -md5 -fingerprint -in certificate.crt

that is: the md5 (or sha1 etc.) key fingerprint of an X509 certificate.

Thanks very much.
Guido
