 ============
 
 The Nginx HMAC secure link module enhances the security and functionality of the standard secure link module.  
-Secure token is created using secure HMAC construction with an arbitrary hash algorithm supported by OpenSSL, e.g., `md5`, `sha1`, `sha256`, `sha512`. Furthermore, secure token is created as described in RFC2104, that is, `H(secret_key XOR opad,H(secret_key XOR ipad, message))` instead of a simple `MD5(secret_key,message, expire)`.
