Configurable Signature Appearance – DigitalSigner 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). Also gives you a special feature invisible signature.

PKI Interoperability – DigitalSigner 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 time-stamp PDF documents for long-term validation purposes. DigitalSigner 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.

SHA1 – Our software can digitally sign and timestamp PDF documents using SHA1.

PAdES Standard – DigitalSigner is compatible with PAdES and PAdES-LTV (Long Term Validation).
