Method

Stringmd5(String s)
md 
try {
    return md5(s.getBytes("UTF-8"));
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
    return "";
byte[]md5(String s)
Get the MD5 of a string 

try {
    return MessageDigest.getInstance("MD5").digest(s.getBytes());
} catch (NoSuchAlgorithmException ex) {
    throw new IOException(ex);
Stringmd5(String s)
md 
MessageDigest md = getMessageDigest("md5");
return bytes2HexString(md.digest(s.getBytes(StandardCharsets.UTF_8)));
byte[]md5(String sInput)
Equivalent to (JavaSE): MessageDigest.getInstance("MD5").digest(sInput.getBytes()); Source: http://www.anavi.org/article/107/ 
int nDigestLen = 16;
byte[] PlainText = sInput.getBytes();
byte[] encryptedText = new byte[nDigestLen];
MessageDigest Cipher;
Cipher = MessageDigest.getInstance("MD5");
Cipher.update(PlainText, 0, PlainText.length);
Cipher.digest(encryptedText, 0, nDigestLen);
return encryptedText;
