My current key pair (ID 0xD7079C77) is a standard 2048-bit RSA key pair created on 28-September-2011. Its fingerprint is:
5E6D 6EAE 16C3 DA75 450B 219C 9A80 4E97 D707 9C77
You can use this to send encrypted mail to me if you like, but please note that I don't always have the appropriate software and keyring to hand, so using it may delay a response.
I also use this key pair to sign the occasional e-mail message or software package to prove that they are from me. If you are going to rely on such signatures, you should probably verify the fingerprint with me personally the first time, and/or encourage someone you already trust to do the due diligence and then sign my public key. If you're already part of the web of trust, you may be able to find a trust path to my key using either my key's statistics page or the following form:
I'd welcome any opportunity to improve my connectivity, so if you're in Edinburgh, Scotland or think we're likely to meet at some conference or other, please get in touch so that we can arrange to sign each other's keys. My Big Lumber page gives details. Please read my key signing policy in advance and come appropriately prepared.
My previous key pair (ID 0xEA2882BB) is a DSS/ElGamal key pair created on 30-April-2002. Its fingerprint is:
C555 B169 838B 1E93 6F1C 397A EF40 FC29 EA28 82BB
I'm no longer soliciting signatures for this key pair, and I no longer use it either to sign messages or other public keys. The main reason for its continued existence is to keep me connected to the strong set while I gather signatures on my current key. Because 1024-bit DSA is no longer regarded as being strong enough for future use, I will revoke this key at some point.
My original key pair was a 1024-bit RSA key pair (ID 0xB566E329) dating back to December 1993. I don't regard that as a secure key size any more, so I have revoked this key to prevent it being used.
