de.das.encrypter.tools.ByteArrayConverter
public class ByteArrayConverter extends Object
This class provides a converter to build string from byte arrays and vice versa, where the byte values greater than "0x7F" will be replaced by the values where the MSB of the byte is set to "0" and the MSB itself is placed as a bit into an appended table.
