# GoCertifi: SSL Certificates for Golang
This Go package contains a CA bundle that you can reference in your Go code.
This is useful for systems that do not have CA bundles that Golang can find
itself, or where a uniform set of CAs is valuable.
This is the same CA bundle that ships with the
[Python Requests](https://github.com/kennethreitz/requests) library, and is a
Golang specific port of [certifi](https://github.com/kennethreitz/certifi). The
CA bundle is derived from Mozilla's canonical set.
## Usage
You can use the `gocertifi` package as follows:
```go
import "github.com/certifi/gocertifi"
cert_pool, err := gocertifi.CACerts()
```
You can use the returned `*x509.CertPool` as part of an HTTP transport, for example:
```go
import (
"net/http"
"crypto/tls"
)
// Setup an HTTP client with a custom transport
transport := &http.Transport{
TLSClientConfig: &tls.Config{RootCAs: cert_pool},
}
client := &http.Client{Transport: transport}
// Make an HTTP request using our custom transport
resp, err := client.Get("https://example.com")
```
## Detailed Documentation
Import as follows:
```go
import "github.com/certifi/gocertifi"
```
### Errors
```go
var ErrParseFailed = errors.New("gocertifi: error when parsing certificates")
```
### Functions
```go
func CACerts() (*x509.CertPool, error)
```
CACerts builds an X.509 certificate pool containing the Mozilla CA Certificate
bundle. Returns nil on error along with an appropriate error code.
