Method

Stringmd5(String input)
md 
String result = input;
if (input != null) {
    MessageDigest md = MessageDigest.getInstance("MD5");
    md.update(input.getBytes());
    BigInteger hash = new BigInteger(1, md.digest());
    result = hash.toString(16);
    while (result.length() < 32) {
        result = "0" + result;
...
Stringmd5(String input)
Create an MD5 hash of a string. 
if (input == null || input.length() == 0) {
    throw new IllegalArgumentException("Input string must not be blank.");
try {
    MessageDigest algorithm = MessageDigest.getInstance("MD5");
    algorithm.reset();
    algorithm.update(input.getBytes());
    byte[] messageDigest = algorithm.digest();
...
Stringmd5(String input)
Returns a MD5 digest string of the input string. 
try {
    MessageDigest md = MessageDigest.getInstance("MD5");
    BigInteger number = new BigInteger(1, md.digest(input.getBytes()));
    String hashtext = number.toString(16);
    while (hashtext.length() < 32) {
        hashtext = "0" + hashtext;
    return hashtext;
...
StringMD5(String inputString)
Used to get the MD5 hash of a given string. 
try {
    MessageDigest messageDigest = MessageDigest.getInstance("MD5");
    byte[] array = messageDigest.digest(inputString.getBytes());
    StringBuffer stringBuilder = new StringBuffer();
    for (int i = 0; i < array.length; ++i) {
        stringBuilder.append(Integer.toHexString((array[i] & 0xFF) | 0x100).substring(1, 3));
    return stringBuilder.toString();
...
Stringmd5(String inputText)
md 
if (inputText == null || "".equals(inputText.trim())) {
    throw new IllegalArgumentException("please input un-null value");
String encryptText = null;
try {
    MessageDigest m = MessageDigest.getInstance("md5");
    m.update(inputText.getBytes());
    byte s[] = m.digest();
...
byte[]md5(String inStr)

    byte[] array = md.digest(md5.getBytes());
    StringBuffer sb = new StringBuffer();
    for (int i = 0; i < array.length; ++i) {
        sb.append(Integer.toHexString((array[i] & 0xFF) | 0x100).substring(1, 3));
    return sb.toString();

Stringmd5(String message)
Encrypt the passed String using MD5. 
try {

    return (hex(md.digest(message.getBytes())));
} catch (NoSuchAlgorithmException e) {
return (null);
