# .NET Dev Certificate Trust on Linux

Get HTTPS working locally on Linux without fighting your browser

## What this does

Running a .NET app locally over HTTPS on Linux often ends in trust errors that are hard to decode. This walks the certificate from being created to being trusted by the system, with steps that differ per Linux flavour. Reach for it when local HTTPS refuses to work and you cannot tell why.

### Top 3 things it does for you

- Fix an untrusted dev certificate on Linux
- Get my local HTTPS site trusted by the system
- Sort out certificate trust inside WSL2
