title: "C05. Use Basic Authentication"

For endpoints that require Basic authentication, pass the username and password to `set_basic_auth()`. cpp-httplib builds the `Authorization: Basic ...` header for you.
|
|
|
|
## Basic usage
|
|
|
|
```cpp
|
|
httplib::Client cli("https://api.example.com");
|
|
cli.set_basic_auth("alice", "s3cret");
|
|
|
|
auto res = cli.Get("/private");
|
|
if (res && res->status == 200) {
|
|
std::cout << res->body << std::endl;
|
|
}
|
|
```
|
|
|
|
Set it once, and every request from that client carries the credentials. No need to build the header each time.
|
|
|
|
## Per-request usage
|
|
|
|
If you want credentials on only one specific request, pass headers directly.
|
|
|
|
```cpp
|
|
httplib::Headers headers = {
|
|
httplib::make_basic_authentication_header("alice", "s3cret"),
|
|
};
|
|
auto res = cli.Get("/private", headers);
|
|
```
|
|
|
|
`make_basic_authentication_header()` builds the Base64-encoded header for you.
|
|
|
|
> **Warning:** Basic authentication **encodes** credentials in Base64 — it does not encrypt them. Always use it over HTTPS. Over plain HTTP, your password travels the network in the clear.
|
|
|
|
## Digest authentication
|
|
|
|
For the more secure Digest authentication scheme, use `set_digest_auth()`. This is only available when cpp-httplib is built with OpenSSL (or another TLS backend).
|
|
|
|
```cpp
|
|
cli.set_digest_auth("alice", "s3cret");
|
|
```
