WoT? [Web Of Trust](https://en.wikipedia.org/wiki/Web_of_trust)

## Why?
Example use case for this repository is [Tor Browser](https://torproject.org/),
I need to download it on most of systems and I need to verify it and it's
painful to verify the PGP key all the time, while I can just verify my own
fingerprint from paper and see that it has signed the keys. I have done this
at least twice on Windowses first installing GPG through Chocolatey.
For example, I use [Tor Browser](https://torproject.org/) everywhere and
download it directly from their website. They have signed it using GPG (a
OpenPGP implementation) and to ensure it hasn't been tampered with, I have
to check that signature and I have two options:
* * * * *
* I can always [verify the signature](https://support.torproject.org/tbb/how-to-verify-signature/),
but that takes time and I would need to verify it from both [support.torproject.org](https://support.torproject.org/tbb/how-to-verify-signature/)
and [4bflp2c4tnynnbes.onion](http://4bflp2c4tnynnbes.onion/#how-to-verify-signature).
But what if [they were compromised or I was under a MITM attack or lazy and verfied only one version](https://www.qubes-os.org/faq/#should-i-trust-this-website)?
* (or) I could verify the signing key carefully once, sign (or certify) it
by myself and in the future simply verify that my own key is valid (as I
have been doing this a few times on the other side of dualbooting and at
family).
I don't know if there is point in putting down formal signing requirements,
but what has been my policy at the time of writing is:
This second method is also [encouraged by Tails](https://tails.boum.org/install/expert/usb/index.en.html).
NOTE: this section is written from memory so may be inaccurate
What if I am wrong and trust the wrong key? I think I am less likely to
trust a wrong key by verifying it carefully and signing it once than
verifying it separately every time. However if I do sign a wrong key, I can
always revoke my signature and then publish the key with my revocation
signature on public keyservers (which I don't usually do, while I cannot
control what people do with the signatures from this repository).
* friends - knowing for a long time through various connections and seeing
at times seeing IDs (or visiting both directions) and otherwise having
so deep relationship that lying about identity wouldn't be easily possible
* privacytools - confirmed from the people themselves, their websites,
privacytools.io (WKD in git) and similar.
* software - used their verification instructions (of varying strength)
* keepassxc.asc mullvad.asc tails.asc tor-browser-developers.asc yggdrasil.asc
* keepassxc - checked their website through normal and Tor Browser
* mullvad - checked their website and onion
* tails - followed their verification instructions (including checking
that it's signed by a Debian developer)
* tor-browser - followed their checking instructions
* yggdrasil - checked their website and comitted apt repo adding to git
## Inclusion policy
* * * * *
* I am reasonably certain that the key belongs to whom it claims to belong
to or I trust the key to belong to whomever it belongs to.
* I have some need of the key or have attended keysigning party with the
key owner.
