Our Encryption Key
We are issuing a new OpenPGP key for security@greywellcyber.com. When it is ready it will be published here as a downloadable file with its full fingerprint, and listed in our security.txt. Any key published on our previous website is retired: please do not use it.
Until the new key is here, send a short first message without the sensitive detail and we will agree a way to receive it.
