This extends nusenu's basic idea of using the stem library to
dynamically exclude nodes that are likely to be bad by putting them
on the ExcludeNodes or ExcludeExitNodes setting of a running Tor.
* https://github.com/nusenu/noContactInfo_Exit_Excluder
* https://github.com/TheSmashy/TorExitRelayExclude
The basic cut is to exclude Exit nodes that do not have a contact.
That can be extended to nodes that do not have an email in the contact etc.
The basic idea is to exclude Exit nodes that do not have ContactInfo:
* https://github.com/nusenu/ContactInfo-Information-Sharing-Specification
That can be extended to relays that do not have an email in the contact,
or to relays that do not have ContactInfo that is verified to include them.
But there's a problem, and your Tor notice.log will tell you about it:
you could exclude the nodes needed to access hidden services or
directorues. So we need to add to the process the concept of a whitelist.
you could exclude the relays needed to access hidden services or mirror
directories. So we need to add to the process the concept of a whitelist.
In addition, we may have our own blacklist of nodes we want to exclude,
or use these lists for other applications like selektor.

That part requires [PyYAML](https://pyyaml.org/wiki/PyYAML)
https://github.com/yaml/pyyaml/
https://github.com/yaml/pyyaml/ or ```ruamel```: do
```pip3 install ruamel``` or ```pip3 install PyYAML```;
the advantage of the former is that it preserves comments.
Right now only the ExcludeExitNodes section is used by we may add ExcludeNodes
later, and by default all sub-sections of the badnodes.yaml are used as a
ExcludeExitNodes but it can be customized with the lWanted commandline arg.
The original idea has also been extended to add different conditions for
exclusion: the ```--contact``` commandline arg is a comma sep list of conditions:
* Empty - no contact info
* NoEmail - no @ sign in the contact',
More may be added later.
(You may have to run this as the Tor user to get RW access to
/run/tor/control, in which case the directory for the YAML files must
be group Tor writeable, and its parents group Tor RX.)
Because you don't want to exclude the introduction points to any onion
you want to connect to, ```--white_onions``` should whitelist the
introduction points to a comma sep list of onions, but is
currently broken in stem 1.8.0: see:
introduction points to a comma sep list of onions; we fixed stem to do this:
* https://github.com/torproject/stem/issues/96
* https://gitlab.torproject.org/legacy/trac/-/issues/25417
```--torrc_output``` will write the torrc ExcludeNodes configuration to a file.
Now for the final part: we lookup the Contact info of every server
that is currently in our Tor, and check it for its existence.
If it fails to provide the well-know url, we assume its a bogus
relay and add it to a list of nodes that goes on ExcludeNodes -
not just exclude Exit.
If the Contact info is good we add the list of fingerprints to add
to ExitNodes, a whitelist of relays to use as exits.
```--proof_output``` will write the contact info as a ciiss dictionary
```--good_contacts``` will write the contact info as a ciiss dictionary
to a YAML file. If the proof is uri-rsa, the well-known file of fingerprints
is downloaded and the fingerprints are added on a 'fps' field we create
of that fingerprint's entry of the YAML dictionary. This file is read at the
beginning of the program to start with a trust database, and only new
contact info from new relays are added to the dictionary.
You can expect it to take an hour or two the first time this is run:
>700 domains.
Now for the final part: we lookup the Contact info of every relay
that is currently in our Tor, and check it the existence of the
well-known file that lists the fingerprints of the relays it runs.
If it fails to provide the well-know url, we assume its a bad
relay and add it to a list of nodes that goes on ```ExcludeNodes```
(not just ExcludeExitNodes```). If the Contact info is good, we add the
list of fingerprints to ```ExitNodes```, a whitelist of relays to use as exits.
```--bad_on``` We offer the users 3 levels of cleaning:
1. clean relays that have no contact ```=Empty```
2. clean relays that don't have an email in the contact (implies 1)
```=Empty,NoEmail```
3. clean relays that don't have "good' contactinfo. (implies 1)
```=Empty,NoEmail,NotGood```
The default is ```=Empty,NotGood``` ; ```NoEmail``` is inherently imperfect
in that many of the contact-as-an-email are obfuscated, but we try anyway.
To be "good" the ContactInfo must:
1. have a url for the well-defined-file to be gotten
2. must have a file that can be gotten at the URL
3. must support getting the file with a valid SSL cert from a recognized authority
4. (not in the spec but added by Python) must use a TLS SSL > v1
5. must have a fingerprint list in the file
6. must have the FP that got us the contactinfo in the fingerprint list in the file,
