Easy integration

We’ve developed unique expertise so you don’t have to!

  • Ties in directly with CertifiO to provide an integrated solution to confirm the origin, integrity and authenticity of your official documents for decades.
  • Does not require any previous experience with digital signatures (ITU X.509), or with PDF standards (ISO 32000), PDF/A (ISO-19005), PAdES (ISO-32000 et ETSI TS 102 778), etc.

The standard version enables your systems to affix a signature area in a PDF document and then sign it with CertifiO, the trusted digital signature. The PDF/A option enables conversion to PDF/A-1, PDF/A-2 and PDF/A-3 standards to ensure longevity and, in the case of PDF/A-3, to attach supporting documents.
