How it works

  • Architecture
  • Features
  • Technical Specifications
  • Optional Modules


Signing Automation Server incorporates functions that provide a set of security and trust mechanisms as services that can be used with different integration strategies:

  • SOAP/WS: Using the OASIS DSS standard as an access protocol for web services
  • REST/WS, SOAP/WS: Using the Entrust Signing Automation Server integration gateway, which supports configuring traffic and data processing with an XML pipeline language
  • Java SDK: For easy integration of electronic signature services in native Java applications

The following diagram illustrates a typical integration of the Entrust Signing Automation Server platform into your organization.

Authentication and Authorization

Supports native authentication methods based on passwords and digital certificates. The validation can be delegated to LDAP/AD.

Object and Entity Management

Manages platform entities and objects. External repositories, such as user LDAP/AD, databases, files, and HSMs can be added for protecting private keys.

Certificate Validation

Provides PKI functions for validating certification chains and querying certificate status. Supports OCSP/CRL and customized mechanisms (e.g., databases).

Signature Creation and Validation

Creates and validates signatures compliant with the PAdES, XAdES, and CAdES standards; including document, email, and web services signatures.

Long-Term Validation (LTV)

Extends a signature’s validity up to the lifetime of the TSA certificate. Cryptographic reliability is preserved, the certification chain is incorporated as well as the certificate status information at the time of signing, and a timestamp.

Auditing and Accounting

Logs are securely stored in a uniform and centralized way. It’s also possible to forward log data to an external SIEM tool for processing and generating a report.
