shred's Issues

Question

Hi,

Does it make a difference to reverse the order of functions? Example:

shredconf := shred.NewShredderConf(&shredder, shred.WriteZeros|shred.WriteRand, 25, true)

What does 1 refer to? Just writing randomly or writing with zeros too? It is the number of iterations of which of the functions? Or both?

Thanks in advance.
