ComputeHash Method
Computes a hash.
Syntax
hash.computeHash([callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
This method computes a hash of the data specified by InputMessage or InputFile. The algorithm used is specified by Algorithm. The HashValue property will be populated with the computed hash.
Input Notes
The class will determine the source of the input based on which properties are set.
The order in which the input properties are checked are as follows:
When a valid source is found the search stops.The Progress event will fire with updates during this operation.
