Features
What Cachet does, point by point: whole batches at once, three signing modes, PAdES levels, template validation and output verified on the spot.
Whole batches at once
Point Cachet at files or folders. The same mark, page and position are applied to every document in the batch.
Three signing modes
A qualified eID signature, an advanced signature from Azure Key Vault, or a plain image stamp with no legal value.
PAdES up to B-LTA
Levels b-b, b-t, b-lt and b-lta, selectable per run. b-lta is the default — the strongest and longest-lasting.
Trusted timestamping
An RFC 3161 timestamp authority proves when you signed. Point it at a qualified TSA when eIDAS-qualified preservation matters.
Long-term validation
CA certificates and OCSP/CRL responses are embedded at signing time, so the PDF stays verifiable after the certificates expire.
Verified on the spot
Each signed file is re-opened and validated, and the achieved level is reported. Levels are never silently downgraded.
Template validation
Inputs are accepted only if their page count and per-page dimensions match a model PDF exactly. Rejected files are never signed.
Click to place
A real preview of the target page, rendered by the bundled PDFium engine. Click where the mark belongs — that is where it is signed.
Visible signature mark
eID signatures stamp the cardholder photo, name and date; Azure signatures stamp the name and date.
Nothing overwritten
Output is written as
{name}_signe.pdfin a folder you choose, and existing files are never replaced.Six languages in the app
The wizard speaks English, French, Dutch, German, Spanish and Portuguese, and follows your system language by default.
Standalone binaries
One windowed app and one console tool per platform, for Linux and Windows. Nothing to install beyond the eID middleware.
