Method

StringbyteToString(byte[] data)
Array of characters is converted to a string 
if (data == null)
    return null;
String result = "";
for (int k = 0; k < data.length; k++) {
    result += Character.toString((char) (data[k]));
return result;
StringbytetoString(byte[] digest)
byteto String 
String str = "";
String tempStr = "";
for (int i = 0; i < digest.length; i++) {
    tempStr = (Integer.toHexString(digest[i] & 0xff));
    if (tempStr.length() == 1) {
        str = str + "0" + tempStr;
    } else {
        str = str + tempStr;
...
StringbyteToString(byte[] input)
Creates a string 
return new String(input);
StringbytetoString(byte[] tb)
byteto String 
StringBuffer tsb = new StringBuffer();
for (int i = 0; i < tb.length; i++) {
    tsb.append(Integer.toHexString((int) tb[i]));
return tsb.toString();
StringbyteToString(final boolean prettyPrint, int byteValue)
Returns a byte value as either a 2-char hex string, or if pretty printing, and the byte value is a printable ASCII character, as a quoted ASCII char, unless it is a single quote character itself, in which case it will still be represented as a hex byte. 
String result = null;
if (prettyPrint) {
    if (byteValue >= START_PRINTABLE_ASCII && byteValue <= END_PRINTABLE_ASCII
            && byteValue != QUOTE_CHARACTER_VALUE) {
        result = String.format(" '%c' ", byteValue);
    } else {
        result = String.format(" %02x ", byteValue);
} else {
    result = String.format("%02x", byteValue);
return result;
StringbyteToString(int[] byteData)
Chang the bit(it's length = 64) into the string. 
StringBuilder str = new StringBuilder();
for (int i = 0; i < 4; i++) {
    int count = 0;
    for (int j = 0; j < 16; j++) {
        int pow = 1;
        for (int m = 15; m > j; m--) {
            pow *= 2;
        count += byteData[16 * i + j] * pow;
    if (count != 0) {
        str.append((char) (count));
return str.toString();
