We released all SetaPDF components in new minor versions!
Beside several bug fixes, small features and tweaks in the SetaPDF-Core component the main reason for this release is the new functionality in the SetaPDF-Signer component that allows you to gather and embed validation related information, such as OCSP responses, CRLs and certificates for LTV (Long-Term Validation).
What does Long-Term Validation mean? We try to explain it in some simple sentences: Each certificate has a fixed period of validity. Also the infrastructure which allows you to ask for revocation information of a certificate may have a limited life-time. Generally speaking: It may be not possible to validate a certificate in the future. The idea behind LTV is that all involved information which was used to validate a signature at a given time are collected and saved. This can be done by embedding them into the PDF itself. The resulting PDF document can be re-signed by a document level timestamp signature then to proof the status at the given date and time. If you want to know more details, please take a look at the current PAdES standard.
The documentation about these new features is available here.
