-It is called with the current buffer containing the HTTP response (without

-;;; Return an HMAC-SHA1 authentication code for KEY and MESSAGE.
-;;;
-;;; KEY and MESSAGE must be unibyte strings. The result is a unibyte
-;;; string. Use the function `encode-hex-string' or the function
-;;; `base64-encode-string' to produce human-readable output.
-;;;
-;;; See URL:<http://en.wikipedia.org/wiki/HMAC> for more information
-;;; on the HMAC-SHA1 algorithm.
-;;;
-;;; The Emacs multibyte representation actually uses a series of
-;;; 8-bit values under the hood, so we could have allowed multibyte
-;;; strings as arguments. However, internal 8-bit values don't
-;;; correspond to any external representation \(at least for major
-;;; version 22). This makes multibyte strings useless for generating
-;;; hashes.
-;;;
-;;; Instead, callers must explicitly pick and use an encoding for
-;;; their multibyte data. Most callers will want to use UTF-8
-;;; encoding, which we can generate as follows:
-;;;
-;;; (let ((unibyte-key (encode-coding-string key 'utf-8 t))
-;;; (unibyte-value (encode-coding-string value 'utf-8 t)))
-;;; (hmac-sha1 unibyte-key unibyte-value))
-;;;
-;;; For keys and values that are already unibyte, the
-;;; `encode-coding-string' calls just return the same string.
