Is there a way I can determine when a particular certificate fingerprint without having the certificate itself?
something like
OpenSSL::X509::Certificate.new("-----BEGIN CERTIFICATE-----\n"+cert+"\n-----END CERTIFICATE-----\n")
but from a certificate fingerprint?
background: i've authentication being done using this certificate and end users are allowed to input either certificate or its fingerprint to enable authentication from my side
I don't believe this will be possible to do the reverse, due to the fact that the fingerprint is generated as a hash, which is a one-way operation.
