GreenDefMF2 is a cryptographic native plugin for the Chrome browser. Developed by greenrail.service, this free add-on falls under the category of Browsers and specifically the subcategory of Add-ons & Tools.

Similar to the GreenDef extension, GreenDefMF2 is designed to add cryptographic functionality to JavaScript code in GreenRail Service products. However, this extension is built on manifest version 2 and is compatible with Chrome browsers up to version 88.

The main functions of GreenDefMF2 include receiving messages from web pages with requests for signing and verifying user data, creating requests for certificates, and performing other cryptographic functions. These requests are then sent to the Native Messaging Host plugin, which utilizes the MS CryptoAPI for implementing cryptographic operations. Finally, the results of these operations are sent back to the web page.

With its focus on cryptographic functionality and compatibility with Chrome, GreenDefMF2 offers users enhanced security and encryption capabilities within the browser environment.
