Reset Method

Resets the hash function context.

Syntax

hashfunction.reset([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

Reset resets the context of the hash function, discarding any data passed to it previously.

Use this method to restart the hash calculation process from scratch.

This method does not affect one-go methods like Hash or HashStream; they reset the hash functioncontext automatically.
