Message Digests in Java 1.5

I'm exploring some of Java's Cryptography Extension. I'm trying to create a function that lets me calculate a hash of some string (for storing passwords in a database, for example). Using various sources (forums.java.sun.com, google, etc.) I ended up with this. It seems to work ok, but I'd like someone else look over my code to see if I missed something.

I wrapped the code in a small application for your compiling/execution comfort.

Code:

---

/**
 * Testing java message digesting.
 *
 * This class should be compiled using JDK 1.5 or higher
 */
import java.security.*;

class MessageDigestingTest
{
  /* Supported Message Digest Algorithms in JDK.5, afaik:
  *
  * MD2
  * MD5
  * SHA-1
  * SHA-256
  * SHA-384
  * SHA-512
  */
  private static final String ALGORITHM = "SHA-512";
  private static final char HEXCHAR[] = {  '0','1','2','3','4','5','6','7', '8','9','a','b','c','d','e','f'};


  public static void main(String[] args)
  {
    if (args.length < 1)
    {
      System.out.println("Usage: MessageDigestingTest toBeDigestedString");
    }
    else
    {
      System.out.println("Digesting using " + ALGORITHM + ": " + args[0]);
      System.out.println(digest(ALGORITHM, args[0]));
    }
  }


  private static String digest(String algorithm, String message)
  {
    /* StringBuilder is new in JDK1.5. It's a faster,
        but thread-unsafe, version of StringBuffer. */
    StringBuilder hexString = new StringBuilder();

    try
    {
      byte[] pwdBytes = message.getBytes();
      MessageDigest md = MessageDigest.getInstance(algorithm);
      md.update(pwdBytes);
      byte[] mesgdig = md.digest();
           
      for (int i=0; i<mesgdig.length; i++)
      {
        int c = ((int) mesgdig[i]) & 0xff;
               
        hexString.append(HEXCHAR[c >> 4 & 0xf]);
        hexString.append(HEXCHAR[c & 0xf]);
      }
    }
    catch (NoSuchAlgorithmException nsae)
    {
      System.err.printf("\nError while hashing password for logging.\nMessage: %s\n", nsae.getMessage());
    }

    return hexString.toString();
  }
}
