X.509 Certificate Testing...

[Milton Smith]

Hi All,

I'm looking for a set of certificates, self-signed certs, cross-signed 
certs, small chains, large chains, different critical and non-critical 
sections, revoked certs, blacklisted certs, invalid, not yet valid, time 
stamped, etc.  I realize it's difficult to be comprehensive but is there 
anything anyone can recommend for unit tests or CD/CI builds?  Trying to 
avoid creating all this if it exists already.  Thanks!

Regards,
Milton
