From 3e0f68fdff1998dae9cb6f8510a3e945a268d1f6 Mon Sep 17 00:00:00 2001 From: Ben McGinnes Date: Tue, 20 Mar 2018 08:07:22 +1100 Subject: example: python bindings encryption * Since we don't want to encourage accessing the low level functions (e.g. op_encrypt), but since this example can still be useful to understand, renaming it and will add new encryption examples to match the instructions in the HOWTO. --- lang/python/examples/encrypt-to-all.py | 53 ------------------------ lang/python/examples/low_level-encrypt_to_all.py | 53 ++++++++++++++++++++++++ 2 files changed, 53 insertions(+), 53 deletions(-) delete mode 100755 lang/python/examples/encrypt-to-all.py create mode 100755 lang/python/examples/low_level-encrypt_to_all.py (limited to 'lang/python/examples') diff --git a/lang/python/examples/encrypt-to-all.py b/lang/python/examples/encrypt-to-all.py deleted file mode 100755 index bad4220c..00000000 --- a/lang/python/examples/encrypt-to-all.py +++ /dev/null @@ -1,53 +0,0 @@ -#!/usr/bin/env python -# -# Copyright (C) 2016 g10 Code GmbH -# Copyright (C) 2008 Igor Belyi -# Copyright (C) 2002 John Goerzen -# -# This program is free software; you can redistribute it and/or modify -# it under the terms of the GNU General Public License as published by -# the Free Software Foundation; either version 2 of the License, or -# (at your option) any later version. -# -# This program is distributed in the hope that it will be useful, but -# WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
