StringMD5(String text)
MD 
MessageDigest md;
md = MessageDigest.getInstance("MD5");
byte[] md5hash = new byte[32];
md.update(text.getBytes("iso-8859-1"), 0, text.length());
md5hash = md.digest();
return convertToHex(md5hash);
StringMD5(String text)
MD 
try {
    MessageDigest md = MessageDigest.getInstance("MD5");
    byte[] md5hash = new byte[32];
    md.update(text.getBytes("iso-8859-1"), 0, text.length());
    md5hash = md.digest();
    return convertToHex(md5hash);
} catch (Exception e) {
return null;
StringMD5(String text)
MD 
return messageDigest(text, "MD5");
Stringmd5(String text)
Encrypt String 
MessageDigest md = MessageDigest.getInstance("MD5");
byte[] b = md.digest(text.getBytes());
int size = b.length;
StringBuffer encryptStr = new StringBuffer(size);
for (int i = 0; i < size; i++) {
    int u = b[i] & 255;
    if (u < 16) {
        encryptStr.append("0" + Integer.toHexString(u));
...
Stringmd5(String text)
returning a MD5 hash string 
try {
    if (text == null) {
        return "";
    byte[] digest = MessageDigest.getInstance("MD5").digest(text.getBytes());
    StringBuffer sb = new StringBuffer();
    for (int i = 0; i < digest.length; i++) {
        sb.append(Integer.toString((digest[i] & 0xf0) >> 4, 16));
...
StringMD5(String text)
This nethod is used for encrypt String to MD5 
String output = null;
try {
    MessageDigest dg = MessageDigest.getInstance("MD5");
    dg.reset();
    dg.update(stringToBytes(text));
    byte[] hasher = new byte[32];
    hasher = dg.digest();
    return bytesToHexString(hasher);
...
Stringmd5(String text)
md 
byte[] bytes = md.digest(text.getBytes());
BigInteger bi = new BigInteger(bytes);
return bi.toString(16);
Stringmd5(String text)
md 
try {
    return hash("MD5", text);
} catch (Exception e) {
    throw new RuntimeException(e);
Stringmd5(String text)
md 
MessageDigest msgDigest = null;
try {
    msgDigest = MessageDigest.getInstance("MD5");
} catch (NoSuchAlgorithmException e) {
    throw new IllegalStateException("System doesn't support MD5 algorithm.");
try {
    msgDigest.update(text.getBytes("utf-8"));
...
byte[]md5(String text, String charset)
Computes an md5 hash of a string. 
if (text == null) {
    throw new NullPointerException("null text"); 
try {
    MessageDigest md = MessageDigest.getInstance("MD5"); 
    md.update(text.getBytes(charset));
    return md.digest();
} catch (NoSuchAlgorithmException e) {
