Method Detail

encodeHex

public static char[] encodeHex(byte[] data)

Converts an array of bytes into an array of characters representing the hexidecimal values of each byte in order. The returned array will be double the length of the passed array, as it takes two characters to represent any given byte.

decodeHex

public static byte[] decodeHex(char[] data)
                        throws java.lang.Exception

Converts an array of characters representing hexidecimal values into an array of bytes of those same values. The returned array will be half the length of the passed array, as it takes two characters to represent any given byte. An exception is thrown if the passed char array has an odd number of elements.
