title: java.security.NoSuchAlgorithmException: Algorithm PBKDF2WithHmacSHA1 not available
body: <p>I have code in java 1.4 version there we got a new requirement like have decrypt a password from another webservice response, for that have to use AES 256 decryption, getting following exception: </p>
  
  <pre><code>SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1"); 
  
  java.security.NoSuchAlgorithmException: Algorithm PBKDF2WithHmacSHA1 not available 
  at javax.crypto.SunJCE_b.a(DashoA12275) 
  at javax.crypto.SecretKeyFactory.getInstance(DashoA12275) 
  at ftpserver.AESEncrypter.main(AESEncrypter.java:107) 
  </code></pre>
  
  <p>I tried by copying jce_policy_1-4 version jars into java home security folder still am getting the above exception.<br>
  Is there any solution in Java 1.4 without changing to 1.5 because running jboss server version 3.2.3 will not support java 1.5.</p>
