# rootcerts
|
||
|
|
|
||
|
|
Functions for loading root certificates for TLS connections.
|
||
|
|
|
||
|
|
-----

|
|
|
||
|
|
Go's standard library `crypto/tls` provides a common mechanism for configuring
|
||
|
|
TLS connections in `tls.Config`. The `RootCAs` field on this struct is a pool
|
||
|
|
of certificates for the client to use as a trust store when verifying server
|
||
|
|
certificates.
|
||
|
|
|
||
|
|
This library contains utility functions for loading certificates destined for
|
||
|
|
that field, as well as one other important thing:
|
||
|
|
|
||
|
|
When the `RootCAs` field is `nil`, the standard library attempts to load the
|
||
|
|
host's root CA set. This behavior is OS-specific, and the Darwin
|
||
|
|
implementation contains [a bug that prevents trusted certificates from the
|
||
|
|
System and Login keychains from being loaded][1]. This library contains
|
||
|
|
Darwin-specific behavior that works around that bug.

## Example Usage
|
||
|
|
|
||
|
|
Here's a snippet demonstrating how this library is meant to be used:
|
||
|
|
|
||
|
|
```go
|
||
|
|
func httpClient() (*http.Client, error)
|
||
|
|
tlsConfig := &tls.Config{}
|
||
|
|
err := rootcerts.ConfigureTLS(tlsConfig, &rootcerts.Config{
|
||
|
|
CAFile: os.Getenv("MYAPP_CAFILE"),
|
||
|
|
CAPath: os.Getenv("MYAPP_CAPATH"),
|
||
|
|
})
|
||
|
|
if err != nil {
|
||
|
|
return nil, err
|
||
|
|
}
|
||
|
|
c := cleanhttp.DefaultClient()
|
||
|
|
t := cleanhttp.DefaultTransport()
|
||
|
|
t.TLSClientConfig = tlsConfig
|
||
|
|
c.Transport = t
|
||
|
|
return c, nil
|
||
|
|
}
|
||
|
|
```
