E-signatures and timestamps on your own server.

QuickSign signs PDFs (PAdES) and CMS with PKCS#11 e-signature tokens and adds RFC 3161 timestamps. One self-contained file for Windows and Linux runs as a REST API or as a command-line tool. Documents never leave your machine; only a hash goes to the timestamp server.

Features

PKCS#11 e-signatures

Sign CMS / PKCS#7 with a USB e-signature token (AKiS, OpenSC-compatible cards). The signer is chosen by national ID, and the right certificate is found among the plugged-in tokens.

PDF signatures with a visible stamp

PAdES signatures that verify in Adobe Acrobat, with a visible signed-by stamp. Several signers can sign one document in a single request, each in their own corner.

RFC 3161 timestamps

Every signature is timestamped. Logs, contracts or any file, or just its hash, can be timestamped without a token. TurkTrust, KamuSM, E-Güven and E-Tuğra are built in.

REST API and CLI

Synchronous and queued signing endpoints with an OpenAPI schema. The same binary runs `sign` and `timestamp` from scripts, cron jobs and CI with meaningful exit codes.

ASiC-S containers and templates

The original file and its signature or timestamp come back in one .asics package. Signature text templates use placeholders such as name, national ID, date and signer order.

Safe PIN handling, no install

PINs are stored encrypted or sent per request; repeated wrong PINs are rejected before they reach the token, so it never locks. Runs as a Windows service or under systemd, with no .NET install.

In code

quicksign · command line

# timestamp a file (no token needed)
quicksign timestamp -f rapor.pdf

# file + timestamp in one .asics package
quicksign timestamp -f rapor.pdf --format container

# sign with the token of the given signer
quicksign sign -f belge.pdf --tckn 12345678901 --pin 1234

How AI fits in

The signing and timestamp core comes from QuickShot's Sign package, so AI agents work here with the same framework skills and rules as in every QuickShot project. Its website and guides are written from the repository itself: the CLI, the signing code and the OpenAPI schema.
