certdump

certdump

This is a very simple (maybe overly so!) x.509 Certificate reader.

certdump contains U.S. Government PIV Certificate support through the pault.ag/go/piv library, and will extract a few PIV specific fields out of the x.509 Certificate.

This is intended to replace basically all usage where you wind up running something like openssl x509 -in something.crt -inform der|pem -noout -text.

Additionally, this contains a json output format, helpful when quickly scripting something over a large number of Certificates.
