Hi everybody I am trying to implement the MD5 algorithm in the Java Snippet Node, but I am unable to run it succesfully.
More specifically I want to "hash" a column and return the MD5 version of that column, to "anonymize" the information of that column.
I found the Java Code in a bunch of websites and I particulary liked this one http://bit.ly/29x4uY6. The code is bellow and also I am attaching a workflow with my attempt.
Any help will be appreciated
Best regards
import java.io.FileInputStream;
import java.io.UnsupportedEncodingException;
import java.math.BigInteger;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
public class MD5 {
public static String getMD5(String input) {
try {
MessageDigest md = MessageDigest.getInstance("MD5");
byte[] messageDigest = md.digest(input.getBytes());
BigInteger number = new BigInteger(1, messageDigest);
String hashtext = number.toString(16);
// Now we need to zero pad it if you actually want the full 32 chars.
while (hashtext.length() < 32) {
hashtext = "0" + hashtext;
}
return hashtext;
}
catch (NoSuchAlgorithmException e) {
throw new RuntimeException(e);
}
}
public static void main(String[] args) throws NoSuchAlgorithmException {
System.out.println(getMD5("Javarmi.com"));
}
}
