Certificate Validity Checks

Checking validity of signer certificates

By default the SignServer checks if the signer certificate of a signer is valid before letting the signer process a request. If the signers certificate is not valid an error message is returned.

There are two properties that can be set to disable this check:

PropertyDescription
CHECKCERTVALIDITYDefault value is true, meaning that the validity period of the certificate will be verified before processing. Set to false to ignore if the certificate is expired or not yet valid.
CHECKCERTPRIVATEKEYVALIDITY

Default value is true, meaning that the validity period in the PrivateKeyUsagePeriod of the certificate will be verified before processing. This is only done if this extension exists (it is optional in a certificate). Set to false to ignore the PrivateKeyUsagePeriod.

MINREMAININGCERTVALIDITY

Default value is 0. This property defines a minimum remaining validity time required of the signing certificate. If the signing certificate expires within the number of days specified an error occurs. Set to 0 (default) to disable this check.
