I started using GPG key as one of my small experiments in March, 2015. Throughout the setup, I made some mistakes, which I revoked later, and explored several usage scenarios. Although like what was said in the post I’m giving up on PGP, I don’t really use the encryption in daily email communication, it is still good to have an online identity.
A year later, which is 3 months before my experimental key expires, I think now is a good time to roll out a new one. I followed Alex’s post Creating the Perfect GPG Keypair to create a signing subkey for daily usage and keep my master key sperately in a safe place. The following is my transition statement.
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 I am transitioning GPG keys from an old 4192-bit RSA key to a new 4096-bit RSA key. The old key will continue to be valid for some time, but I prefer all new correspondance to be encrypted in the new key, and will be making all signatures going forward with the new key. This transition document is signed with both keys to validate the transition. If you have signed my old key, I would appreciate signatures on my new key as well, provided that your signing policy permits that without reauthenticating me. The old key, which I am transitioning away from, is: pub 4096R/30A45011B233544E 2015-03-21 [expires: 2017-03-22] Key fingerprint = 6ECD C5B8 235C D44D 2471 866E 30A4 5011 B233 544E The new key, to which I am transitioning to, is: pub 4096R/44D10E44730992C4 2016-12-04 [expires: 2018-12-04] Key fingerprint = 85DF A3EB 72CD DE7D 3F2A 127C 44D1 0E44 7309 92C4 To fetch the full new key from a public key server using GnuPG, run: gpg --keyserver hkps://hkps.pool.sks-keyservers.net --recv-key 44D10E44730992C4 If you have already validated my old key, you can then validate that the new key is signed by my old key: gpg --check-sigs 44D10E44730992C4 If you then want to sign my new key, a simple and safe way to do that is by using caff (shipped in Debian as part of the "signing-party" package) as follows: caff 44D10E44730992C4 Please contact me via e-mail at <[email protected]> if you have any questions about this document or this transition.
