Comparison and difference between CAs
While doing some Google searches, I learnt that there are a lot of different Certification Authorities like the Windows role named "Active Directory Certificate Services", the OpenSSL library or the EJBCA software.
I would like to know the differences between them knowing that they all issues certificates and act as a certification authority if I'm not wrong?
Do they work differently? Are they all compliant with X.509 for example?
