for (int n = 0; b != null && n < b.length; n++) {
    stmp = Integer.toHexString(b[n] & 0XFF);
    if (stmp.length() == 1)
        hs.append('0');
    hs.append(stmp);
return hs.toString().toUpperCase();
StringbyteArrayToHexString(byte[] b)
byte Array To Hex String 
StringBuffer buf = new StringBuffer();
for (int i = 0; i < b.length; i++) {
    int j = b[i] & 0xFF;
    buf.append(hexDigits.charAt(j / 16));
    buf.append(hexDigits.charAt(j % 16));
return buf.toString();
StringbytesToHexString(byte[] bytes)
bytes To Hex String 
StringBuffer sb = new StringBuffer();
for (int i = 0; i < bytes.length; i++) {
    String hex = Integer.toHexString(0xFF & bytes[i]);
    if (hex.length() == 1) {
        sb.append('0');
    sb.append(hex);

byte[]hex2byte(byte[] b)
hexbyte 
if ((b.length % 2) != 0)

StringtoHex(byte[] buf)
to Hex 
if (buf == null)
    return "";

StringtoHex(byte[] data)
Converts byte data to a Hex-encoded string. 
StringBuilder sb = new StringBuilder(data.length * 2);

StringtoHexString(byte[] b)
Convert a byte array to a hex string. 
StringBuffer sb = new StringBuffer(b.length * 2);

StringtoHexString(byte[] buf, int offset, int length)
to Hex String 
StringBuilder output = new StringBuilder();

    output.append(' ');
...
StringtoHexString(byte[] data)
Converts a byte array into a String of its hexadecimal representation. 
int c;
String res = "", s;
for (byte aux : data) {
    c = aux & 0xff;
    s = Integer.toHexString(c);
    if (s.length() == 1)
        res += "0";
    res += s;
