# Crystal Lang Digest Auth

[![CI](https://github.com/spider-gazelle/digest-auth/actions/workflows/ci.yml/badge.svg)](https://github.com/spider-gazelle/digest-auth/actions/workflows/ci.yml)

Communicate with servers that implement digest auth.

## Installation

1. Add the dependency to your `shard.yml`:

   ```yaml

   dependencies:

     digest-auth:

       github: spider-gazelle/digest-auth

   ```

2. Run `shards install`

## Usage

```crystal

require "http/client"

require "digest-auth"

# New client per-connection, this keeps track of nonce count

digest_auth = DigestAuth.new

uri = URI.parse "http://foo.com/posts?id=30&limit=5"

# if you expect digest auth use a head request to get the challenge header

client = HTTP::Client.new uri

response = client.head uri.full_path

response.status_code # => 401

challenge = response.headers["WWW-Authenticate"]

uri.user = "username"

uri.password = "password"

# Generate the auth header, need to indicate if talking to IIS

auth_header = digest_auth.auth_header(uri, challenge, "get", iis: false)

# Make the request

response = client.get uri.full_path, HTTP::Headers{ "Authorization" => auth_header }

response.status_code # => 200

# Make a second request while the connection is still open

uri.path = "/posts/30"

auth_header = digest_auth.auth_header(uri, challenge, "post", iis: false)

response = client.post uri.full_path, HTTP::Headers{ "Authorization" => auth_header }, body: "hello!"

response.status_code # => 201

```

or using `.before_request`

```crystal

require "http/client"

require "digest-auth"

digest_auth = DigestAuth.new

uri = URI.parse "http://foo.com/"

client = HTTP::Client.new uri

response = client.head uri.full_path

response.status_code # => 401

challenge = response.headers["WWW-Authenticate"]

uri.user = "username"

uri.password = "password"

client.before_request do |request|

  req_path = URI.parse request.resource

  uri.path = req_path.path

  uri.query = req_path.query

  auth_header = digest_auth.auth_header(uri, challenge, request.method, iis: false)

  request.headers["Authorization"] = auth_header

end

client.get "/"

client.post "/some_path", body: "hello!"

```
