hmac.update()

hmac.update(data[, input_encoding])

Updates the Hmac content with the given data, the encoding of which is given in input_encoding and can be 'utf8', 'ascii' or 'binary'. If encoding is not provided, and the data is a string, an encoding of 'utf8' is enforced. If data is a Buffer then input_encoding is ignored.

This can be called many times with new data as it is streamed.
