パッケージ: python3-certvalidator (0.11.1-4)

Validates X.509 certificates and paths

Is a Python library that offers functionality for validating X.509 digital certificates. It is used to verify the security and integrity of X.509 certificates, which are widely used in Internet security systems such as TLS/SSL, email encryption, and more.

The certvalidator library performs the following main tasks:

 - Certificate Validation: The library checks the validity of X.509
   digital certificates. This includes checking the certificate signature,
   expiration date, issuing authority (CA), certificate revocation, and
   other important properties.
 -  Chain of Trust: It helps to build and validate the certificate chain,
   that is, the sequence of certificates that links a specific certificate
   to a trusted certification authority (root CA).
 - CRL (Certificate Revocation Lists) Check: The library checks whether a
   certificate has been revoked by querying Certificate Revocation Lists
   (CRLs) published by certification authorities.
 - Online Certificate Status Protocol (OCSP) Check: In addition to CRL
   checking, certvalidator can check the status of a certificate through
   the Online Certificate Status Protocol (OCSP) to determine whether the
   certificate is still valid.
 - Custom Expiration Policy: You can configure and apply custom validity
   policies to meet specific certificate validation requirements.
 - Extensibility: The library is designed to be extensible and customizable,
