This update for ssh-audit fixes the following issues:
ssh-audit was updated to version 2.5.0
- Fixed crash when running host key tests.
- Handles server connection failures more gracefully.
- Now prints JSON with indents when -jj is used (useful for
debugging).
- Added MD5 fingerprints to verbose output.
- Added -d/--debug option for getting debugging output.
- Updated JSON output to include MD5 fingerprints. Note that
this results in a breaking change in the 'fingerprints'
dictionary format.

rsa-sha2-512 and rsa-sha2-256.
- Added OpenSSH v8.6 & v8.7 policies.
- Added 3 new key exchanges:
+ gss-gex-sha1-eipGX3TCiQSrx573bT1o1Q==
+ gss-group1-sha1-eipGX3TCiQSrx573bT1o1Q==
+ gss-group14-sha1-eipGX3TCiQSrx573bT1o1Q==

hash.

Update to version 2.3.0
The highlight of this release is support for policy scanning
(this allows an admin to test a server against a
hardened/standard configuration).
- Added new policy auditing functionality to test adherence to
a hardening guide/standard configuration
(see -L/--list-policies, -M/--make-policy and -P/--policy).
- Created new man page (see ssh-audit.1 file).
- 1024-bit moduli upgraded from warnings to failures.
- Many Python 2 code clean-ups, testing framework improvements,
pylint & flake8 fixes, and mypy type comments.

(see --lookup)
- Suppress recommendation of token host key types.
- Added check for use-after-free vulnerability in PuTTY v0.73.
