The main function of PDF Signer is to sign PDF documents using X.509 digital certificates. Using this product you can quickly sign multiple PDF files (bulk sign) by selecting input and output directory. This is ideal for bulk signing of a large number of corporate documents rather than signing each one individually.
- Support for Smart card certificates (qualified certificates)
- Batch (bulk) digital signature (sign an entire folder)
- Command line parameters, PowerShell scripting
- Time Stamping
- SHA 256/512 support
- PAdES Part 2 and LTV (Long Term Validation)
- Embedding Revocation Information for the signing certificate (CRL, OCSP)
Configurable Signature Appearance – PDF Signer provides a fully configurable appearance for its digital signatures. The positioning of the signature appearance is configurable, plus on which pages of the document it should appear (first page, last page or all pages).
PKI Interoperability – PDF Signer is completely PKI neutral and will work with PKI components from any vendor (this includes CAs, certificates, CRLs, smartcards, etc.).
Timestamping – Like signatures, timestamps are easier to verify when they’re associated with a timestamp authority’s trusted certificate. Including a timestamp helps to prove that the document wasn’t changed after you had signed it and it reduces the chances of an invalid signature.
Long-term validation purposes – Using our software you can sign and timestamp PDF documents for long-term validation purposes. PDF Signer supports advanced digital signatures which include embedded RFC 3161 compliant secure timestamps. Such signatures can be verified even after the signer’s certificate expires or is revoked.
SHA 256, SHA 512 algorithms and RSA 2048 – Our software can digitally sign and time stamp PDF documents using SHA 256 or SHA 512 hash algorithms (also known as SHA2 algorithms) and RSA 2048 or higher key length according to ETSI TS 102 176-1 V2.0.0.
PAdES standard – PDF Signer is compatible with PAdES Part 2 (ETSI TS 102778-2)
Invoice signing – PDF Signer allows organizations to digitally sign and process large numbers of invoices. EU VAT Directive requires that: “Invoices sent by electronic means shall be accepted by Member States provided that the authenticity of the origin and integrity of the contents are guaranteed”. The only standard and interoperable way of doing this is to use digital signatures and in general EU member states require that a qualified electronic signature is used to confirm the identity of the originator.
