title: how to use `PBKDF2WithHmacSHA1And8bithow` in bc-java or jdk8?
body: <p>I have used this encryption method in Android and there is no problem
  But I will report an error when I transplant it to jdk
  How to solve the problem?
  I tried bc-java but I did not run.</p>
  <p>my code is:</p>
  <pre><code>public static void main(String[] args) {
      try {
          SecretKeyFactory.getInstance(&quot;PBKDF2WithHmacSHA1And8bit&quot;);
      } catch (NoSuchAlgorithmException e) {
          e.printStackTrace();
      }
  }
  </code></pre>
  <p>and jdk8 error:</p>
  <pre><code>java.security.NoSuchAlgorithmException: PBKDF2WithHmacSHA1And8bit SecretKeyFactory not available
  </code></pre>
