TLS Root CAs

Initially a HTTP context will not trust any root-CAs at all. Which root-CAs to trust must be explicitly specified via the add-root-CA service command(s).

RootCertChains can be used to easily select a particular chain of trusted root-CAs with multiple HTTP contexts, without having to re-send each of the root-CA commands for each HTTP context. The maximum number of RootCertChains that can exist for a HTTPC service session handle, is only 1.

Error codes

Error code Description
0xd8a0a03c The HTTPS server's TLS certificate is signed by an unknown/not-trusted root CA.
0xd8a0a046 This is returned by HTTPC:Initialize when no network connection is available(or at least when wifi is disabled via Home Menu on New3DS).
0xd8a0a066 This indicates that the context handle is wrong.
