Certificate Revocation List Check Tool is designed to enhance security by performing several key functions related to executable files (EXE). It can scan your client for EXE files and examine their code-signing certificates. The tool also searches for the relevant CRL to determine whether it can be downloaded. It validates the integrity of the certificate chain, checks both the certificate and CRL for expiration dates, and can export a comprehensive list of all gathered information as a file. Additionally, it cross-references to ensure you are not using any revoked certificates, helping maintain a secure environment.
