Mobile signing

Documents which are to be signed are first hashed by ADSS Signing Server and this hash value is then sent to the signer’s mobile device for signing. The user’s signing key can be held in a software app on the mobile device or within a micro SD card or even within the mobile SIM.

Signature verification

You can programmatically verify signed documents coming into an organisation for automated Straight Through Processing (STP). ADSS Server supports multiple PKI trust points, detailed verification reports, dynamic certificate path discovery and full certificate validation using real-time certificate status checking. Signature and certificate quality checking using the latest PEPPOL quality-rating scheme is also available.

On Demand Server Side Signing

Get any document (PDF, Word, Excel etc.) digitally signed by sending it to ADSS Signing Server. Created digital signatures are long term i.e. with embedded revocation and timestamp information:
Any type of document (PDFs, Word, Excel, Proprietary Format, etc.)

Signed document with option of embeding RFC3161 Timestamps and OCSP certificates status information (meeting XAdES, CAdES & PAdES specifications). Any business application can interface with ADSS Signing Server using watched Folder Integration, ADSS Client SDK, XML/SOAP web services or email integration using ADSS Secure Email Server.

Signature verification

Verify digital signatures on documents by sending them to ADSS Signing Server (Verification Mode). Digital signatures are verified using the OCSP/CRL based revocation information (checked embedded or real time) using either the verification time based on machine clock, signing time or timestamp time:
Any type of document (Signed PDFs, other type of documents wrapped inside XML DigSig or PKCS#7/CMS, signed emails S/MIME)

Verification Response status can be Trusted, Not Trusted or Indeterminate (Low-level details also provided for signer, issuing authorities, signature, evidence (OCSP, CRLs), timestamps, signature and certificate quality levels).
To protect document confidentiality and ensure higher transfer speed, business applications can choose to only send the document hash and signature value for verification to ADSS Signing Server.

Local Signing (client-side)

Create client side/local digital signatures using USB/Smart Card, Windows Keystore or MAC (Keychain):

Signing outbound emails

Sign all outbound emails and attachments using a centrally held corporate key:
Signing outbound emails
Request for the signing of email attachments (e.g. PDF, XML, etc.) or for signing of the whole email or hash of the email content
Signed attachment (e.g. signed PDF), or whole signed email (S/MIME) or raw signature

Verifying incoming emails

Verify all digitally signed incoming emails and signed attachments:
Verification Request may be required for signed attachments (signed PDFs etc.) or for the whole signed email
Verification Report + evidence information (CRLs, OCSP, timestamp)
