2# Desc: Wrapper for ots-git-gpg-wrapper
3# Note: Required because git's gpg.program option doesn't allow you to set
4# command line options.
5# Usage: git -c gpg.program=<path to ots-git-gpg-wrapper.sh> commit -S
6# Input: file: $HOME/.local/share/ots/jsonrpc_url.txt # first line is JSON RPC
7# url for local bitcoin node containing login credentials. Example:
8# http://user:35z8deadbeefhrdeadbeef5rk3@192.168.86.1:8332/
9# Depends: ots 0.7.0 (see https://github.com/opentimestamps/opentimestamps-client )
10# Version: 0.0.6
