jkolezyn / cert_tree

Simple script to view a chain of x509 certificates stored in a single PEM file as a tree. It also enables viewing expiry dates and purging expired certificates. It uses openssl under the hood. It builds the tree looking only at Subject and Issuer fields. It does NOT validate the certificate chain.

Thanks. What python version are you using?

I will look into this when I have some free time.

Yes, so this is actually the answer. F-strings are available from Python 3.6.

I will try to change this not to use f-strings when I have more time.
