sig!3 entry vs sig! entry on certain GnuPG keys from the PuTTY software site

2006-08-25 Thread synth_spring
The web site for the PuTTY software provides GnuPG keys to verify downloads of 
the PuTTY software. see 
http://www.chiark.greenend.org.uk/~sgtatham/putty/keys.html

With these keys imported into the GnuPG public keyring, issuing gpg 
--check-sigs produced the following output (the user name has been redacted):

4 signatures not checked due to missing keys


For the self-signatures on the DSA-type keys (and only the DSA-type keys) there 
is a sig!3 entry instead of a sig! entry. The other signatures on the 
DSA-type keys just have a sig! entry. It has been said elsewhere that the 3 
in the sig!3 entry indicates a certificate check level of 3. However, the 3 
does not appear on the self-signature entries for the RSA-type keys. Is this to 
do with the key types (the DSA type and the RSA type), the way that the keys 
were created and/or signed, or some other reason?

It's to do with the way the keys were signed at the time they were
generated.

There is a default certification level option that can be used either
on the command line or in a config file - normally GnuPG will ask you
for the certification level when you sign a key, but the default /can/
be used if the right options are set, and /will/ be used at the time of
key generation.

I believe you will not normally be asked for a cert-level, at least
not with most recent versions of gpg (I forget when that changed
exactly).  You must set ask-cert-level in your config or on the
command line to be prompted.
