Akamai token validation module for Nginx

Validates Akamai v2 query string tokens

Installation

Add --add-module when configuring nginx:

./configure --add-module=$PATH_TO_AKAMAI_TOKEN_VALIDATE

Requires OpenSSL.

Configuration

akamai_token_validate

• syntax: akamai_token_validate token
• default: off
• context: http, server, location

Sets the value of the token that should be validated. The parameter value can contain variables, e.g. $arg_token.

akamai_token_validate_key

• syntax: akamai_token_validate_key key_hex
• default: empty
• context: http, server, location

Sets the secret key

akamai_token_validate_uri_filename_prefix

• syntax: akamai_token_validate_uri_filename_prefix prefix
• default: none
• context: http, server, location

Defines a set of prefixes that will be matched against the URI file name, only URIs whose file name starts with one of the defined prefixes will require a token

akamai_token_validate_strip_token

• syntax: akamai_token_validate_strip_token param_name
• default: none
• context: http, server, location

This setting can be used to strip query parameters, set it to the name of the parameter to strip. The default behavior is not to strip any query parameters. This setting is useful when the validated requests are proxied to some upstream server (using proxy_pass) - it can be used to remove the token from the upstream request

Sample configuration

The following configuration requires a token parameter named token, either as a query string parameter or as a cookie:

http {

	server {

		if ($arg_token) {
			set $test_token $arg_token;
		}

		if ($cookie_token) {
			set $test_token $cookie_token;
		}

		location /protected/ {
			akamai_token_validate $test_token;
			akamai_token_validate_key 1234;
		}
	}
}

A protected URL may look something like: http://domain/protected/?token=st=1498386079~exp=1498386379~acl=/protected/*~hmac=3fea342b4b69149f8a34ff709913ad8676a3495172e4ac3f387b23554aa3a761
