How to Properly Store and Name Origin Server Certificates in Home Assistant OS

[2006ciro]

Hello everyone,

I need guidance on the correct path (directory) to place my Origin Server SSL certificate and private key so that Home Assistant OS can read them. I also want to confirm if Home Assistant OS has the necessary read permissions for the recommended directory. Additionally, what are the proper file names and extensions I should use to ensure an end-to-end secure connection?

Here are the key points I’m looking to clarify:

The recommended directory/path for the certificate (.crt or .pem) and private key (.key or .pem) when using Home Assistant OS.
Whether Home Assistant OS automatically grants itself the necessary read permissions in that directory.
The correct naming conventions for these files (e.g., fullchain.pem, privkey.pem) or whether alternative names/extensions are acceptable.
Any advice or best practices would be greatly appreciated. Thanks!
