Enigma plugin on Windows

[MichelFR]

Hi,

I am currently using Roundcube that includes the Enigma plugin on my Windows 7 computer.
Knowing that the plugin is not supposed to be used on Windows, I was wondering about whether there can be an alternative or solution to make Roundcube able to sign and encrypt emails (perhaps by installing Crypt_GPG via Pear). Do you think it can be possible ?

Moreover, having Pear and GnuPG (with its binaries) installed, do you think I can exploit Enigma using an alternative way ?

Thank you for your help.
