title: "GPG Key Update"

Hello everyone! Writing this quick article to announce the rotation and subsequent retiring of my old GPG key to a new one! I'm doing this mainly because my key has grown rather large, and I'd like to transition my key from using a 4096-bit RSA key to a Ed25519 key, which should provide functionally the same amount of security (author of Ed25519 quotes it equivalent to ~3000 bit RSA key, but I do know that really isn't the best way to compare these two things :P )

So, with this announcement, I'd like to make the following points:
* My old key is not compromised, but will be revoked after making this announcement
* I will *not* use my old key to sign things, encrypt things, or authenticate with anything from this point onwards. If I do, something is terribly wrong.
* This new key has been cross signed by my old key, but I won't be cross signing my old key with my new one, since that seems to be a "can go either way" situation in this case, and I don't see the benefit as the key is being revoked regardless.

This is the information of the key that is being revoked:
```
pub   rsa4096 2020-09-29 [C]
      2BC5D27B47EE5632F97A668012FAE298AAD38D3D

sub   rsa4096 2020-09-29 [S] [expires: 2022-10-03]
```

And this is the information of my new key:
```
pub   ed25519 2022-02-21 [C]

sub   ed25519 2022-02-21 [A] [expires: 2023-02-21]
```

I'd recommend to update your keychains if you happen to have my key, and the key hosted on the homepage of this website has been updated to reflect my new key.
