# (c) 2018 Dale Phurrough
|
||||||
|
# Licensed under the Mozilla Public License 2.0
|
||||||
|
#
|
||||||
|
# Allows GnuPG to prompt and read passphrases by the pinentry standard
|
||||||
|
# with a GUI when running within WSL (Windows Subsystem for Linux).
|
||||||
|
# Works for all keys managed by gpg-agent (GPG, SSH, etc).
|
||||||
|
# This is a drop-in GUI alternative to pinentry-curses, pinentry-gtk-2, etc.
|
||||||
|
# https://www.gnupg.org/software/pinentry/index.html
|
||||||
|
#
|
||||||
|
# Setup:
|
||||||
|
# 1. Save this script and set its permissions to be executable
|
||||||
|
# 2. Configure gpg-agent to use this script for pinentry using
|
||||||
|
# one of the following methods:
|
||||||
|
# a) Set pinentry-program within ~/.gnupg/gpg-agent.conf
|
||||||
|
# pinentry-program /mnt/c/repos/pinentry-wsl-ps1/pinentry-wsl-ps1.sh
|
||||||
|
# b) Set the path to this script when you launch gpg-agent
|
||||||
|
# gpg-agent --pinentry-program /mnt/c/repos/pinentry-wsl-ps1/pinentry-wsl-ps1.sh
|
||||||
|
# 3. Optionally enable persistence of passwords.
|
||||||
|
# Requires https://github.com/davotronic5000/PowerShell_Credential_Manager
|
||||||
|
# Please follow instructions there to install from the Gallery or GitHub.
|
||||||
|
# Note security perspectives like https://security.stackexchange.com/questions/119765/how-secure-is-the-windows-credential-manager
|
||||||
|
# Possible values for PERSISTENCE are: "", "Session", "LocalMachine", or "Enterprise"
|
||||||
|
# 4. Optionally disable toast notification of password retrieval from Credential Manager.
|
||||||
|
# By default, this code notifies you with a toast notification every time gpg-agent
|
||||||
|
# retrieves a password from the Windows Credential Manager. Gpg-agent caches passwords
|
||||||
|
# by default (see gpg-agent settings like max-cache-ttl) so you may not see the notification
|
||||||
|
# with every usage.
|
||||||
|
# * Disable: edit the script, near the top, set NOTIFY to the value "0"
|
||||||
|
# * Enable: edit the script, near the top, set NOTIFY to the value "1"
