2009-12-09 Thread marco.pallotta
Martin, to say the truth I wanted to test this issue with newer version
of seahorse, because I'm not sure that the bug was really solved by
seahorse developers (ok, the tab trusted keys was removed but the
issue was not only related to this) but I couldn't (as bug #493473).

Thanks for opening a new bug to separate the real bug from the tab
issue.

It doesn't really matter. I chose invalid, because the bug has been
filed about some part of a software that no longer exists.

Martin, why did you mark the bug as invalid? It was a true issue, in fact 
seahorse developers removed Trusted Keys tab in version 2.27. 
I think the bug should be marked as fix released.

Last upstream comment:

In 2.27 the Trusted Keys tab was removed.

Closing as invalid then.

2009-08-24 Thread Markus Gut
This is indeed an issue, since from the web of trust perspective, a user
should trust the key itself only if it is valid.

By setting trust in a key, you actually only trust keys signed by that
key.

See: http://www.gnupg.org/documentation/faqs.en.html#q4.7

I've commented on this more detailed, upstream:

Yes, it's reproducible.

- open seahorse
- press find remote keys
- search a key and import it (the key is put under other collected keys tab)
- open the property window of the imported key
- go to trust tub
- check I have checked that this key belongs to '.'
- close the property window
- you will see that the imported key is put under trusted keys tab

This is wrong for me, as I haven't signed it yet and the signing is
mandatory to set a key trusted.

2009-02-13 Thread marco.pallotta
Sebastien, I read many times that key signing and, if I am not wrong, is a 
process that permits to you to validate a key (that is you hare sure that the 
owner of the key is right). Then, based on the signature, you can trust the 
owner of the key assigning trust level from 1 (don't know) to 4 (I trust fully).
I think trusting a user key without signing is not useful as I declare that I 
don't know if the key is valid or not.

From gpg mini howto
(http://dewinter.com/gnupg_howto/english/GPGMiniHowto-3.html#ss3.6)


3.6 Key signing

As mentioned before in the introduction there is one major Achilles'
heel in the system. This is the authenticity of public keys. If you have
a wrong public key you can say bye bye to the value of your encryption.
To overcome such risks there is a possibility of signing keys. In that
case you place your signature over the key, so that you are absolutely
positive that this key is valid. This leads to the situation where the
signature acknowledges that the user ID mentioned in the key is actually
the owner of that key. With that reassurance you can start encrypting.

Using the gpg --edit-key UID command for the key that needs to be signed
you can sign it with the sign command.

You should only sign a key as being authentic when you are ABSOLUTELY
SURE that the key is really authentic!!!. So if you are positive you got
the key yourself (like on a key signing party) or you got the key
through other means and checked it (for instance by phone) using the
fingerprint-mechanism. You should never sign a key based on any
assumption.

Based on the available signatures and ownertrusts GnuPG determines the
validity of keys. Ownertrust is a value that the owner of a key uses to
determine the level of trust for a certain key. The values are

* 1 = Don't know
* 2 = I do NOT trust
* 3 = I trust marginally
* 4 = I trust fully

If the user does not trust a signature it can say so and thus disregard the 
signature. Trust information is not stored in the same file as the keys, but in 
a separate file.

2009-02-13 Thread Michael Bienia
Setting trust is separate from signing a key (at least from gpg's POV).
Your trust settings are local and not exported with the key like a
signature.

You can trust a key you didn't sign (if it's wise to do so is an other 
question) and you can also distrust a key you did sign.
gpg uses the trust to compute how much it can trust (key-) signatures made by 
that key. So it's possible that you trust a key you didn't sign because you 
trust enough people who signed this key.

[Bug 328735] Re: a key is put in trusted keys without it is signed

2009-02-13 Thread marco.pallotta
Michael I know that trusting and signing are technically two separate 
processes, but I also say again that from a logical point of view trusting 
should follow signing, that is I should assign a trust judgement to key (that 
is to person) that I know that are valid (that is the owner of that key is the 
person that I think he should be). 
The only reason I see to let the user to trust a key without signing it is 
related to a scenario in which the user (owner of the keyring) wants to assign 
trust judgements to people that he knows using the keys that are related to 
these people regardless to the fact that these key are really valid or not. 
That is collecting a sort of people trust list. In this scenario however that 
dangerous thing is that if the user discovers that a key isn't valid he 
should delete it but doing this he should also delete the trust judgement to 
that person; to the other side, in order to preserve trust judgement, he 
shouldn't delete the key once discovered that it isn't valid, but doing this he 
should have in his keyrings not valid keys in which either keys not yet checked 
for validity or keys already checked for validity (but not deleted) should 
cohabit togheter.
I think actual situation is misleading for the user and not very useful.
