Settings: ltv
The long term validation (LTV) settings for signatures.
A signature without LTV requires an online service of the certificate issuer in order to check the validity of the signature certificate. The validity of an LTV signature can also be checked if the service is not available. All information on validation is created at the time of signing and saved in the PDF.
signoSign/Universal will automatically use LTV if all conditions are fulfilled. The data required for this are mainly created from the certificate chain of the signature certificate. To prevent unnecessary downloads of the chain, the keystore of the certificate should also contain its certificate chain.
The following settings are possible in settings.properties with the prefix “ltv.”
