I use my personal S/MIME certificate, issued by CAcert, with most of my email correspondence. If you wish to send me encrypted email and do not have a PGP key, you should download this beforehand.
I am able to offer 15 points to those I assure as part of CAcert's Web of Trust programme. It is available to anyone able to get to either Hatfield or Stevenage, in Hertfordshire.
I am also willing to sign PGP keys. My key is in the strong set.
In late 2011 I migrated to a new 4096-bit RSA key pair. If you have signed my old key (0x6DC48D95), please read the transition statement and consider signing my new key too.
pub 4096R/427543E0 2011-11-01 [expires: 2014-10-31] Key fingerprint = 4242 E30A 4F8B 8638 0014 D2E7 33D5 5277 4275 43E0 uid Nicholas Shanks uid Nicholas Shanks <email@example.com> uid Nicholas Shanks <firstname.lastname@example.org> uid [jpeg image of size 13154] sub 4096R/270F69F3 2011-11-01 [expires: 2014-10-31]
For reference, here is my retired DSA/ElGamal key:
pub 1024D/6DC48D95 2005-12-01 Key fingerprint = 970A 4C6D A94D A4CC D1F7 9928 0511 C4A0 6DC4 8D95 uid Nicholas Shanks <email@example.com> uid Nicholas Shanks <firstname.lastname@example.org> sub 2048g/BE6CADEC 2005-12-01
I will no longer use this key to make new signatures, however it will remain active until all pertanent signatures have been migrated.
My policy for signing keys is that I must have met you face-to-face, seen either your passport, or two other forgery-resistant photo IDs (e.g. foreign driving license and national identity card), and that you assert that the fingerprint I have for your key is correct.
I will then corrispond with you using this key and you must decrypt and reply before I will sign that UID. I will sign photo UIDs and name-only UIDs on the basis of the meeting alone, and either exchange these at the meeting, or forward them to a verified email address. I will not upload your signed key to a keyserver unless you request that I do, and I ask that you do not upload my key either.
Generally I use level 2 signatures, however if you are very familiar to me and we have known one another over a period of several years, I will use a level 3 signature. If you can only provide one photo ID which is neither a passport , I will use a level 1 signature.
If you will be bringing identity documents from countries other than the United Kingdom, Ireland or Germany, you should inform me before the meeting so that I can familiarise myself with the anti-forgery properties of your documents.
Lastly, I maintain my owner-trust database, and recommend that you do the same. An easy-to-understand demonstration of owner-trust is presented in the KGpg Manual, specifically where it refers to a character called George.
