Richard Clayton's PGP keys and policies

Summary

Use the key 0x5F5B9E39 with PGP v5 (v6, v7, v8...)

If you must encrypt using PGP v2.x.x (why?) then use 0xDCABB485

My long-term signing key is 0x7CF07A65, but please do not use this key for encrypting any traffic.

Email addresses

I have a number of working email addresses. My ancient Demon Internet account richard AT happyday.demon.co.uk is no more. Other addresses that I have used, and that all still work are:

The following addresses may still work, but probably not forever:

These addresses, once associated with keys, no longer work at all:

Keys

In the beginning (1 JAN 1997) I had two RSA (v2.6.x) PGP keys:

being ancient v2.6.x keys they never expire. They are cross-signed to show their equivalence. The first of these can be viewed as my long term identity since its main use these days is for signing other more transient keys.

If you are still using PGP v2.x.x then please use the 0xDCABB485 key for encrypted traffic -- since a signing key should not be used for secrecy!

After 1999 I used 2048/1024 DH/DSS keys (for use with PGP5 and PGP6), going to 3072/1024 at the end of 2015. My habit has been to change key on a reasonably regular basis, and to sign the new key with the key that was about to expire (so you can see a thread of trust running through all of these). They are also all signed by 0x7CF07A65 -- my long term identity key.

My current key (which is the one I use for day-to-day signing and from which you should use the sub-keys for day-to-day encryption) is:

it will expire on 1 January 2030. It has a set of shorter lived confidentiality sub-keys.

The Regulation of Investigatory Powers Act

I am subject to United Kingdom laws. Under the RIP Act 2000 it is possible for law enforcement (and other bodies) to request that encrypted material sent to me is put into an intelligible form. This part of the Act came into force in October 2007. If I wished to comply with such a request I would do this by providing them with the session key for a particular message -- thereby preserving the confidentiality of all other messages sent to me. However, in some circumstances it will be lawful for my private key to be requested and, in even more exotic circumstances, for it to be an offence for me to tell people that my key has been seized. At the time of writing, early January 2025, you will be pleased to know that no notices of any kind have been served on me.
