Long-Term Validation (LTV) signatures in Docotic.Pdf 9.7

[Bit Miracle Support]

Docotic.Pdf 9.7 has arrived - find it on our site and NuGet.

The ability to embed long term validation (LTV) information for digital signatures is the key feature of this version.

LTV signatures are crucial for ensuring that a document's authenticity can be verified long after signing. Starting from version 9.7, the library can embed essential validation data - such as certificate revocation lists (CRLs) and Online Certificate Status Protocol (OCSP) responses - directly into the PDF. As a result, even if the original certificate authorities and validation sources become unavailable, the document remains verifiable.
