Where the time goes

Typical signing software is built around one document at a time. With invoices, payslips or test reports, that turns into hours of clicking. This tool processes a whole folder and records the result for each file.

What it should do

• Sign a whole folder or watch a folder for new files
• Use a certificate from the Windows store, a file or a token
• Create PAdES signatures with RFC 3161 timestamps
• Optionally place a visible signature on the page
• Verify the resulting signature
• Keep a clear log of succeeded and failed files

Who it is for

• Accounting and payroll departments
• Laboratories and companies issuing certificates and reports
• Public bodies and organisations with high document volumes

Frequently asked questions

Will the signature be qualified?

That depends on the certificate and device. A qualified signature needs a qualified certificate with the key on a qualified device (QSCD). Otherwise it is an advanced signature or seal.

Is one PIN enough for a whole batch?

That depends on the token and the certificate issuer’s rules. Some devices require a PIN for every signature, and the software has to respect that.

Are documents uploaded to a server?

No. Documents are signed on your computer. For a timestamp, only the document’s hash is sent to the authority.
