D-Bus -based service to simplify interaction with certificate authorities

 Certmonger is a D-Bus -based service which attempts to simplify
 interaction with certifying authorities (CAs) on networks which use
 public-key infrastructure (PKI).
 If it knows the location of a certificate, certmonger can track the
 expiration date and notify you when the certificate is about to expire.
 If it has access to the corresponding private key and information about
 the CA which issued the certificate, certmonger can even attempt to
 automatically obtain a new certificate.
 Supports certificate and key storage in PEM or NSSDB formats.
 Can self-sign certificates, or can submit them to either certmaster or
 development versions of IPA.
