Our DSS services respond to two protocols: the Signature Protocol and the verification protocol which offer the following services:

  • Electronic Signature.
  • Signature verification.

The last service (Verification) performs two functions:

  • Verification or validation of any XADES signature.
  • Signing Expansion.

Regarding the Electronic Signature Service, the user send EADTrust his or her service request with the document to sign indicating the type and the format of signature that he or she wanted.

This same request is required for the Signature Verification Service. The user indicates the document to verify, the signature to expand and the type of signature that he or she wanted.

Considering the Certificate Validation is required to the signature validation, the DSS EADTrust services checks the entire trust chain in addition to the certificate validation.
