All I do is host a public key for John Salter: 10A2154B is his keyID.
Public Key Fingerprint: E081 E193 E3E4 9900 0EEE 5E42 72DA 75C6 10A2 154B
His key can be downloaded at https://saltie.uk/10A2154B.txt.
Beware - it's quite large for a PGP public key, as it has an embedded 64kb photo.
I have another copy without the photo here.
