Contact

I live in Royston near Cambridge in the east of England.

You can contact me by telephone (+447840191336), email, signal and skype. Signal, which is secure and end-to-end encrypted, can be used for video and voice calls as well as text messages.

For one-to-one communication I recommend the telephone and signal, with video calls by arrangement. Zoom and Microsoft Teams are used for videoconferencing. Skype is deprecated, being insecure, but use it if you must.

For encrypting messages it is better to use signal rather than email, but if you wish to communicate with me via encrypted email, first send an S/MIME-signed message with a request to share confidential information, and I shall reply in kind.

If you wish to share encrypted files, such as via a cloud server, please contact me first so that we can exchange PGP keys. Do not use PGP for encrypting email messages. Use S/MIME for that purpose.

Whenever I am electronically incommunicado for longer than a day, there should be an email auto-responder in place to inform you of my whereabouts.
