Method

Stringmd5fromFile(String path)
This function is passed a File name and it returns a md5 hash of this file. 
return md5fromFile(new File(path));
Stringmd5Hex(String data)
Calculate MD5 hash of a string and output in hexadecimal format. 
byte[] byteData = data.getBytes(StandardCharsets.UTF_8);
MessageDigest md = null;
try {
    md = MessageDigest.getInstance("MD5");
} catch (NoSuchAlgorithmException e) {
    throw new RuntimeException(e);
byte[] byteDigest = md.digest(byteData);
...
Stringmd5Hex(String data)
md Hex 
if (data == null) {
    throw new IllegalArgumentException("data must not be null");
byte[] bytes = digest("MD5", data);
return toHexString(bytes);
Stringmd5Hex(String message)
Calculate the MD5 hash of message and return a hex encoded representation of it. 
try {
    MessageDigest md = MessageDigest.getInstance("MD5");
    return hex(md.digest(message.getBytes("UTF8")));
} catch (NoSuchAlgorithmException e) {
    throw new RuntimeException(e); 
} catch (UnsupportedEncodingException e) {
    throw new RuntimeException(e);
Stringmd5Hex(String message)
Return an MD5 hex digest for the given message. 
try {
    MessageDigest md = MessageDigest.getInstance("MD5");
    return hex(md.digest(message.getBytes("CP1252")));
} catch (NoSuchAlgorithmException e) {
} catch (UnsupportedEncodingException e) {
return null;
Stringmd5Hex(String message)
md Hex
