A server-side, digital signature software, the SignServer:
The SignServer is intended for use in environments where central management of cryptographic keys are desired:
The SignServer provides a simple method for administering centrally managed signatures in different applications.
The private signature key is kept within signing tokens. Multiple types of tokens are supported by the SignServer and can be used simultaneously by different signing applications running on the same server. For instance:
Three kinds of services are included in the SignServer:
In addition to processable services, there also exists another concept called Timed Service - which is plug-ins run at defined intervals, performing maintenance or reporting routines.
Running in production for months and years — virtually without downtime — SignServer was designed for high availability and allows you to:
Using the unique plug-in architecture of SignServer, makes it easier than ever to build customized signers for your specific needs. Plug-ins can be uploaded, installed, configured and put in production - all while the SignServer is running.
The Signserver comes with a built-in plug-in for a Time stamp server (TSA). The TSA is RFC 3161 compliant and can be used to generate digitally signed time stamps. Time stamps are normally used together with eSignatures to provide proof of when documents were signed.
The SignServer's PDF signer adds server generated digital document signatures to any received PDF. Thanks to a flexible authorization system you can easily control who is allowed to sign PDF documents. Generated PDF signatures can optinally include time stamps and validation information suitable for long term archival. The PDF signer is ideal for organizationally authenticated documents such as receipts, invoices and regulatory documents. Simple configuration of multiple signers even makes it possible to create server generated personal signatures.
The Signserver comes with a built-in plug-in for Machine Readable Travel Document signing. MRTD is implemented throughout the world, within electronic passports mandated by ICAO.
