certview
What
certview is a GUI aiming to help when working with digital certificates, eg: check the certificate chain for a service including the CA. We are all fans of openssl but it gets a little bit messy if you have a few certs on the table so I wanted a point-and-click workbench for digital certificates.
certview can:
- open x509 PEM coded certificates.
- check the certificate chain for a service online.
- include the toplevel CA if exists in ca cert store (downloaded updated from: mozilla-curl cacert.pem bundle.
- open several certs or cert-chains at the same time.
- view the base64 encoded PEM, the TEXT view (openssl info), the RAW bytes and the log of connections.
- test and do maths and play with the embedded ipython console.
- and probably more.
It is (will be) free software, developed using python3 and PyQt5, and looks like this:
Show me the code!
DISCLAIMER: current code is quick-and-dirty (especially dirty) transition from terminal oneliners to GUI heavily based on things like "subprocess.run()" for openssl exec (not necessary bad in this case imho) and string parse. I consider this a demo to work on. Sorry no code is linked here so far. ¯\_(ツ)_/¯
