/**
* This format supports Shared Key authentication for the 2009-09-19 version of the Blob and Queue
* services. Construct the CanonicalizedResource string in this format as follows:
*
* <p>1. Beginning with an empty string (""), append a forward slash (/), followed by the name of
* the account that owns the resource being accessed.
*
* <p>2. Append the resource's encoded URI path, without any query parameters.
*
* <p>3. Retrieve all query parameters on the resource URI, including the comp parameter if it
* exists.
*
* <p>4. Convert all parameter names to lowercase.
*
* <p>5. Sort the query parameters lexicographically by parameter name, in ascending order.
*
* <p>6. URL-decode each query parameter name and value.
*
* <p>7. Append each query parameter name and value to the string in the following format, making
* sure to include the colon (:) between the name and the value:
*
* <p>parameter-name:parameter-value
*
* <p>8. If a query parameter has more than one value, sort all values lexicographically, then
* include them in a comma-separated list:
*
* <p>parameter-name:parameter-value-1,parameter-value-2,parameter-value-n
*
* <p>9. Append a new line character (\n) after each name-value pair.

* Constructing the Canonicalized Headers String
*
* <p>To construct the CanonicalizedHeaders portion of the signature string, follow these steps:
*
* <p>1. Retrieve all headers for the resource that begin with x-ms-, including the x-ms-date
* header.
*
* <p>2. Convert each HTTP header name to lowercase.
*
* <p>3. Sort the headers lexicographically by header name, in ascending order. Note that each
* header may appear only once in the string.
*
* <p>4. Unfold the string by replacing any breaking white space with a single space.
*
* <p>5. Trim any white space around the colon in the header.
*
* <p>6. Finally, append a new line character to each canonicalized header in the resulting list.
* Construct the CanonicalizedHeaders string by concatenating all headers in this list into a
* single string.
