XEnc for Firefox, XML Encryption Component

A Windows component for strong XML encryption in Firefox applications

Feature-Rich XML Encryption for Firefox

XEnc for Firefox, XML Encryption Component by Lizard Labs offers robust client-side XML encryption and decryption within Firefox-based applications. Targeted primarily toward developers, this component follows the W3C XML Encryption standard and supports a wide range of cryptographic scenarios using X.509 certificates.

Wide Compatibility and Windows Integration

One of the key advantages of XEnc for Firefox is its solid integration with the Windows platform. As a standalone installation, it relies on Microsoft’s standard cryptographic APIs instead of requiring extra libraries like MS XML or CAPICOM. This reduces dependency issues and simplifies deployment in both legacy and modern Windows environments, including Windows XP SP2, Vista, 7, and newer versions.

Flexible Browser and Application Support

XEnc is delivered as an XPCOM component for Mozilla Firefox, enabling encryption functionality in web apps using JavaScript. There is also an ActiveX counterpart for Internet Explorer, desktop applications, and scripting environments like VBScript, allowing developers to implement consistent XML encryption across different platforms and browsers.

Strong Standards Compliance

The component adheres to encryption standards set out by the World Wide Web Consortium (W3C) and the Internet Engineering Task Force (IETF), ensuring compatibility with numerous existing XML security libraries and frameworks, such as Microsoft .NET and ASP.NET. It provides an API that offers precise control over encryption and decryption, facilitating integration into custom workflows or complex security models.

X.509 Certificate and Unicode Support

XEnc for Firefox supports the Windows user certificate store, enabling developers to utilize a variety of secure devices for encryption keys, including smart cards and USB tokens. This boosts security in environments where hardware-based key storage is mandatory. Comprehensive Unicode support ensures proper handling of multilanguage XML documents, making the component suitable for international applications.

Usability and Deployment

Offering a straightforward API, developers can quickly incorporate strong encryption without an extensive learning curve. The standalone installer simplifies the setup process, and because there is no reliance on secondary components, potential conflicts or software version mismatches are minimized.

Performance and Limitations

While the reliance on native Windows APIs provides efficient processing of encryption tasks, functionality is inherently limited to the Windows operating system. Additionally, with modern Firefox limiting support for legacy XPCOM components, compatibility with the latest browser releases may require additional configuration or may not be assured.

Summary

XEnc for Firefox, XML Encryption Component stands out as a practical solution for developers needing reliable client-side XML encryption in Windows and Firefox environments. It balances strong security with ease of use, broad cryptographic support, and convenient deployment options — though its appeal is naturally limited to those working within Windows ecosystems and slightly dated browser technology.
