Java Security

Hello All,

I am trying to troubleshoot a class that a previous colleague/developer wrote that used 3DES encryption. Up until today, the app and class were functioning correctly.

Snippet of method:

...

try {
   Cipher myCipher = Cipher.getInstance("DES.....");
   myCipher.init(Cipher.ENCRYPT_MODE, myKey);

   byte[] inByte = myEncryptedString.getBytes("UTF8");
   byte[] outByte = cipher.doFinal(inByte);

   BASE64Encoder myEncoder = new BASE64Encoder();
   newEncryptedString = myEncoder .encode(output);
}

.....

Unfortuantely I have little experience with java.crypto and would ask for any help in troubleshooting the following exception I'm receiving:

Invalid key length: 24 bytes

Thanks for any help you might be able to suggest!!
