In order to validate, the application should specify that a block list check is carried out and – if this fails – an OCSP check (online status check) all certificates are to be checked for blocking. With this setting, Sign Live! C.C.C delivered.
- If a document is not validated despite having a valid signature, check the settings. To do this, open the settings dialog (menu item "Tools> Settings"), navigate to the "Signatures> Signature Validation> Certificate Validation " and answer the question "Which certificates should be checked using OCSP?" with "All certificates".
- Please make sure that the checkboxes "Restriction list check" and "Online status check" are activated.
Checking the signature again should produce a valid result.
Note:
Various trust centers have discontinued checking by blacklist and currently only use OCSP responders.
