TLS Root CAs[edit]

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 an user-process, is only 2.

When using the context-specific RootCA commands such as HTTPC:AddTrustedRootCA where HTTPC:SelectRootCertChain was already used, the cert will just be added to the selected RootCertChain.

ClientCert Contexts[edit]

These are basically the same as RootCertChains except for TLS client cert+privk. The maximum number of ClientCert-contexts that can exist for an user-process, is only 2.

Error codes[edit]

Error code Description
0xd8a0a03c Failed to verify the HTTPS server's TLS certificate.
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). Seems to be caused by DNS lookup failure(SOCU:getaddrinfo returning an error).
0xd8a0a049 Seems to be caused by a socket connect() timeout error?
0xd8a0a066 This indicates that the context handle is wrong.
0xd820a069 This is returned when the call times out (with any call with a timeout arg)
