Gets or sets a flag that allows signing with a certificate whose validity period has not started yet. The default value is false: signing with such a certificate throws GroupDocsSignatureException, and the document is not signed.
publicboolAllowNotYetValid{get;set;}
Remarks
Validators report a signature made before the certificate becomes valid as not valid. Such a certificate was usually issued for a later date, or the computer’s clock is wrong. When this property is true, the document is signed, and a warning is written to the logger set in SignatureSettings.
The certificate is compared with the current time in UTC. The flag applies to the same certificates as AllowExpired, which controls certificates whose validity period has ended.
