#477 Support for Custom CA's

Opened by wandering213 · 5/28/2026

I'm behind a corporate proxy, when I try to connect to the extension store TLS validation fails due to TLS inspection on our end. Please add support for either specifying a custom CA or using the system CA certs or both.

hey @wandering213 - what URL are you connecting to to get the extensions?

wandering213 commented 6/1/2026, 11:27:12 AM

I can confirm that if I set DENO_TLS_CA_STORE=system that I'm able to connect now. It would be helpful if this was default behavior or was easily set via config.

Thank you @wandering213! I'm on this.

@wandering213 - system is part of the default, along with mozilla - for the bundled Mozilla's CA Certificate Program. So I think we are satisfying your requirements now. Can you verify?

I pulled the latest version and if I remove the 'DENO_TLS_CA_STORE=system' from the environment then, I get an UnknownIssuer error when I run 'swamp update' or 'swamp extension search'. Is that what you mean when you were asking to verify?
