ssh-pageant-wrap
Elementary wrap around ssh client from "Git for Windows" to interact with PuTTY's pageant ssh-agent.
Install
The application is written on C++11 and depends on standard libraries and WinAPI only. CMake >3.2 is used to configure build environment. But actually it's simple enough to build manually.
