sealsign Digital Signature Software

QuoVadis sealsign® software provides the capability for enterprises to easily integrate digital signatures into existing systems and processes including document management systems, archiving systems, ERP, and other workflows.

The sealsign digital signature and validation software supports the legally binding signing of any electronic file.  With the use of digital signatures, the recipient is assured of the authenticity and integrity of a file/document, as well as the time of its creation.

sealsign offers detached signatures (CMS/PKCS#7 as described in IETF RFC 5652) as well as the generation of embedded signatures for PDF, UN/EDIFACT or XML documents.

If required, external time-stamps from the QuoVadis Qualified Time Stamp Authority can be embedded or used separately. In addition, sealsign supports the verification of all supported signature types and can create an archival validation report.

sealsign supports encryption and decryption of documents and data using digital certificates.

The sealsign solution is platform-independent with supported operating systems including Oracle® Java™, Microsoft® Windows®, Linux, UNIX, or Solaris. Alternatively, sealsign is offered as a turnkey appliance including server, operating system, HSM, and sealsign software.

sealsign supports signature creation devices (SSCD) including USB tokens and smart cards, HSMs (Hardware Security Modules), and soft-tokens (PKCS#12 / P12 files). Multiple devices can be used simultaneously.

sealsign is highly scalable and is well-suited for high volume signing activity.

sealsign can be called via a web service, but also delivers a file-based interface, or access using an SDK (Java or .NET) that is integrated directly into applications. Integration into existing environments is fast and easy with sealsign.
