Method

Stringmd5(final String string)
Get the md5 hash of a string. 
return md5HashString(string);
Stringmd5(final String text)
md 
try {
    final byte[] bytesOfMessage = text.getBytes("UTF-8");
    final MessageDigest md = MessageDigest.getInstance("MD5");
    final byte[] digest = md.digest(bytesOfMessage);
    return new String(digest);
} catch (Exception e) {
    throw new RuntimeException();
Stringmd5(InputStream input)
md 
try {
    return digest(input, "MD5");
} catch (NoSuchAlgorithmException e) {
    throw new RuntimeException(e);
Stringmd5(InputStream is)
md 
MessageDigest digest = MessageDigest.getInstance("MD5");
byte[] buffer = new byte[8192];
int read = 0;
while ((read = is.read(buffer)) > 0) {
    digest.update(buffer, 0, read);
byte[] md5sum = digest.digest();
BigInteger bigInt = new BigInteger(1, md5sum);
...
Stringmd5(java.lang.String message)
Creates an MD5 digest from the message. 
try {
    MessageDigest md = MessageDigest.getInstance("MD5");
    StringBuilder sb = new StringBuilder();
    byte buf[] = message.getBytes();
    byte[] md5 = md.digest(buf);
    for (byte aMd5 : md5) {
        String tmpStr = "0" + Integer.toHexString((0xff & aMd5));
        sb.append(tmpStr.substring(tmpStr.length() - 2));
...
Stringmd5(Object content)
md 
String keys = null;
if (content == null) {
    return null;
try {
    MessageDigest md = MessageDigest.getInstance(MD5_NAME);

byte[] buf = new byte[1024];
MessageDigest complete = MessageDigest.getInstance("MD5");
int read;
try (InputStream is = Files.newInputStream(path)) {
    do {
        read = is.read(buf);
        if (read > 0) {
            complete.update(buf, 0, read);
...
Stringmd5(String content)

    for (int i = 0; i < thedigest.length; i++) {
        chars[i * 2] = hexDigits[thedigest[i] >>> 4 & 0xf];
        chars[i * 2 + 1] = hexDigits[thedigest[i] & 0xf];
    return new String(chars);
} catch (NoSuchAlgorithmException e) {
    e.printStackTrace();
return null;
Stringmd5(String content)
md 
if (content == null) {
    return null;
String md5 = null;
try {
    MessageDigest mdEnc = MessageDigest.getInstance("MD5");
    mdEnc.update(content.getBytes(), 0, content.length());
    md5 = new BigInteger(1, mdEnc.digest()).toString(16);
...
Stringmd5(String content)
md 
return base64en.encode(md5.digest(content.getBytes("utf-8")));
