Where is the details of extension of Safari 8 is s

Question

I want to install the safari extension in Safari v8 in Yosemite(Mac OS 10.10) by programmatically. As in safari v5,v6,v7 for extension details, safari maintain Extensions.plist which is stored at ~/Library/Safari/Extensions/Extensions.plist. But in safari v8 there is no information in Extensions.plist for installed extensions like extension is enabled or not.

So is there anyone who knows how safari v8 stores its Extensions information and where?

Answer 1

Since safari 6.2, 7.1 and 8.0 it is stored as binary plist in ~/Library/Keychains/login.keychain as a generic password with title "Safari Extensions List"

You can access it by the Keychain.app or /usr/bin/security or security framework
