Python library for interacting with OpenSSH Certificates

Project description

ssh_certificate_parser is a small library for interacting with OpenSSH host/user certificates. Specifically, it supports RSA, DSA, and Ed25519 keys signed by an RSA certificate authority. It does not currently validate the CA signature, but merely parses out some fields.

remaining_seconds_of_validity = cert.remaining_validity
