method Cipher.prototype.update
Cipher.prototype.update(data: BinaryLike): BufferDeprecated
Updates the cipher with data. If the inputEncoding argument is given,
the dataargument is a string using the specified encoding. If the inputEncodingargument is not given, data must be a Buffer, TypedArray, or DataView. If data is a Buffer,
TypedArray, or DataView, then inputEncoding is ignored.
The outputEncoding specifies the output format of the enciphered
data. If the outputEncodingis specified, a string using the specified encoding is returned. If nooutputEncoding is provided, a Buffer is returned.
The cipher.update() method can be called multiple times with new data until cipher.final() is called. Calling cipher.update() after cipher.final() will result in an error being
thrown.
