New idea: Ability to get Public Key Algorithm and Signature Algorithm in certifications

[csabka]

Over the time algorithms are getting weak. It can be good to create alerts / visualization in case of mass replacements.
It can be good to see when there is a replacement of a cert and after it there is a client issue after that time (which e.g using too old library).

examples:
Signature Algorithm: sha256WithRSAEncryption
Public Key Algorithm: rsaEncryption RSA Public-Key: (2048 bit)

Signature Algorithm: ecdsa-with-SHA256
Public Key Algorithm: id-ecPublicKey Public-Key: (256 bit) ASN1 OID: prime256v1 NIST CURVE: P-256
