16-bit, 32-bit MD5 encryption implementation method for strings under Java programming _java

The

looks like this:

 package cn.sunzn.md5;
Import Java.security.MessageDigest;

Import java.security.NoSuchAlgorithmException;
  public class Str2md5 {public static void main (string[] args) {MD5 ("SUNZN");
    private static string MD5 (String sourcestr) {string result = ' ";
      try {messagedigest MD = messagedigest.getinstance ("MD5");
      Md.update (Sourcestr.getbytes ());
      byte b[] = Md.digest ();
      int i;
      StringBuffer buf = new StringBuffer ("");
        for (int offset = 0; offset < b.length; offset++) {i = B[offset];
        if (i < 0) i = 256;
        if (I <) buf.append ("0");
      Buf.append (integer.tohexstring (i));
      result = Buf.tostring ();
      System.out.println ("MD5 (" + sourcestr +) = "+ result);
    System.out.println ("MD5 (" + Sourcestr + ",) =" + buf.tostring (). SUBSTRING (8, 24));
    catch (NoSuchAlgorithmException e) {System.out.println (e);
   } return result; }
}

MD5 (sunzn,32) = 40379db889f9124819228947faaeb1f7
MD5 (sunzn,16) = 89f9124819228947

The above is a small series for everyone to bring the Java programming string 16 bits, 32-bit MD5 encryption to achieve the full content of the method, I hope to help you, a lot of support cloud Habitat Community ~
