License value unclear in __version__.py #144
Description
In sshkey_tools/version.py, the license value __license__ = "GnuPG 3.0" is ambiguous. GnuPG may refer to GNU Privacy Guard but this doesn't clarify the licensing data.
Based on the rest of the available information and the usage of GPL, it may be inferred that PG may refer to General Public for the GPL license, but this is still unclear and leads parsers to infer a non-standard license.
Ideally, this value should be updated to an SPDX standard value such as GPL-3.0-only or GPL-3.0-or-later.
Thank you! I'm happy to contribute the change if you let me know which license value you'd like to have.
