Digital signature software – SignServer Enterprise

A server-side, PKI-based digital signature software used to sign digital documents, PDFs and code

Electronic vs digital signatures

Electronic signatures, Digital signatures, e-sign, e-signature… There are many names for digital signatures, and our digital signature software SignServer Enterprise enables them all. Server side digital signatures give maximum control and security, allowing your staff and applications to conveniently sign code, digital documents and PDFs. SignServer Enterprise comes as our turn-key SignServer Appliance, SignServer Cloud or as flexible software, described below.

This is our digital signature software

SignServer Enterprise is a server-side digital signature software, based on PKI signing used to sign any digital document. Use SignServer Enterprise to sign code, PDFs, ePassports, and more.

  • A digital signature software with high performance and high availability.
  • Operates on behalf of business applications.
  • Designed to perform automated signatures (and other cryptographic operations on digital documents).
  • SignServer Enterprise is easy to adapt to customer specific needs by using plug-ins.

Time stamp authority

To generate digitally signed time stamps SignServer Enterprise can be used as the time stamp unit within a Time Stamp Authority (TSA). Offering both RFC 3161 and MS Authenticode time-stamps, SignServer Enterprise includes monitoring of time synchronization compliant with the strictest regulations.

Time stamps are normally used together with eSignatures to provide proof that a document existed before a certain time, and can also be used together with advanced signatures to ensure long-term validation of archives.
