Determining the Level of Trust of a Digitally Signed Document

2009-07-08 16:38:37 +0000

In order to determine how trustworthy a digital signature of a file is, you need to grab the file, the digital signature, and you will need to import the user’s public key. This wikipedia fragment describes what is meant by a “trustworthy signature” in terms of the Web of Trust.

This is the command I run to determine the level of trust of my signed foaf file.
<br /> gpg --verify --no-tty --status-fd 2 --command-fd 0 foaf.rdf.asc foaf.rdf<br />

Which results in the folowing output :
<br /> gpg: Signature made Wed 3 Jun 23:19:52 2009 BST using RSA key ID 51F2F7EF<br /> [GNUPG:] SIG_ID foL1PiWCT+546VnE17UG2QvWJeE 2009-06-03 1244067592<br /> [GNUPG:] GOODSIG 9ED0B04E51F2F7EF Mischa Tuffield ([email protected]) <[email protected]><br /> gpg: Good signature from "Mischa Tuffield ([email protected]) <[email protected]>"<br /> gpg: aka "Mischa Tuffield (http://id.ecs.soton.ac.uk/person/6914) <[email protected]>"<br /> [GNUPG:] VALIDSIG 18A2AF280CA59E77AE512BB39ED0B04E51F2F7EF 2009-06-03 1244067592 0 4 0 1 2 00 18A2AF280CA59E77AE512BB39ED0B04E51F2F7EF<br /> [GNUPG:] TRUST_ULTIMATE<br />

This is an automatic way of evaluating how trust worthy statement at the end of a URI are.

Hello All,

I had one of my hard-drives fail miserably a couple of weeks ago, and have only now recovered all of my blog content from Google’s and Yahoo’s caches. I have recreated all of the content, and have set up a cronjob to backup my sql tables, I had copies of most of the important stuff on my machine, and only lost my sql tables … d’oh….

I have set the following 301 redirects from all of the old URLs, I don’t think I have missed any out. Do shout if you find any old broken URLs on my site.

I have used Jules blog post to have a go at iPhone tethering and it seems to work fine. Make sure that if you attempt to tether you should use Jules’s update’d howto on 2009-06-18. All you have to do is point your iPhone at the following url http://www.jules.fm/files/uk.o2.mobileconfig and you can follow the instruction on how to run it here http://richardlai.xanga.com/704930537/enable-tethering-on-iphone-30—too-easy-worldwide-carriers/
