Method

StringtoHexa(byte[] bb)
to Hexa 
char[] ret = new char[bb.length * 2];
for (int i = 0; i < bb.length; i++) {
    ret[i * 2] = HEXA_CHARS[((bb[i] & 0xF0) >> 4)];
    ret[i * 2 + 1] = HEXA_CHARS[((bb[i] & 0x0F))];
return new String(ret);
StringtoHexAddress(long address)
to Hex Address 
return "0x" + Long.toHexString(address).toUpperCase();
StringtoHexaDecimal(byte[] bytesToConvert)
to Hexa Decimal 
final char[] hexCharactersAsArray = "0123456789ABCDEF".toCharArray();
final char[] convertedHexCharsArray = new char[bytesToConvert.length * 2];
for (int j = 0; j < bytesToConvert.length; j++) {
    final int v = bytesToConvert[j] & 0xFF;
    convertedHexCharsArray[j * 2] = hexCharactersAsArray[v >>> 4];
    convertedHexCharsArray[j * 2 + 1] = hexCharactersAsArray[v & 0x0F];
return new String(convertedHexCharsArray);
...
StringtoHexadecimal(byte[] digest)
to Hexadecimal 
String hash = "";
for (byte aux : digest) {
    int b = aux & 0xff;

...
StringtoHexadecimal(byte[] digest)
Convierte un arreglo de bytes a String usando valores hexadecimales 
String hash = "";
for (byte aux : digest) {
    int b = aux & 0xff;
    if (Integer.toHexString(b).length() == 1)
