Certificate Authority

The hu.gs certificate has fingerprint: 93:6D:6D:DA:EE:D9:B6:F6:24:87:11:7C:87:4C:B9:B1, and a copy of the fingerprint signed by David Ford's public key is available here.

To install the certificate into your browser, you should click on the following and verify that the fingerprint matches the signed version: Certificate Authority Certificate
