PBKDF2WithHmacSHA512 SecretKeyFactory not available

Question

This is a really odd error. On two machines, the code is running perfectly. I just set this up on a brand new machine and this isn't working. I'm getting the following error when running the script;

java.lang.RuntimeException: java.security.NoSuchAlgorithmException: PBKDF2WithHmacSHA512 SecretKeyFactory not available

The line of code that is causing the error is;

SecretKeyFactory secretKeyFactory = SecretKeyFactory.getInstance( "PBKDF2WithHmacSHA512" );

Using JDK 1.7.0

The code is all compiling correctly, it is just failing at run time on this line. I have a feeling this is some how related to a JAR file that is different or a JDK that is slightly different, but after checking everything across the different machines, everything looks identical.

Thoughts?

Answer 1

Support for PBKDF2WithHmacSHA512 was added in Java 8, it is not available in Java 7 by default (Java 7 itself only supports PBKDF2WithHmacSHA1).

Compare:

• SecretKeyFactory Algorithms for Java 7

  PBKDF2WithHmacSHA1 Constructs secret keys using the Password-Based Key Derivation Function function found in PKCS #5 v2.0.

• SecretKeyFactory Algorithms for Java 8

  PBKDF2With<prf> Password-based key-derivation algorithm found in PKCS #5 2.0 using the specified pseudo-random function (<prf>). Example: PBKDF2WithHmacSHA256.

So you need to either upgrade to Java 8, or downgrade to PBKDF2WithHmacSHA1, or check if there is a JCE provider that provides PBKDF2WithHmacSHA512 for Java 7 (for example, Bouncy Castle).

If your code is running ok on another machine with Java 7, then check if lib/ext of that Java install contains additional libraries, for example Bouncy Castle has a JCE provider that supports PBKDF2WithHmacSHA512. In that case, you will need to include that same library in the Java install of the other machine.

I was getting the same error because I was running a unit test with PowerMockRunner, i.e.:

@RunWith(PowerMockRunner.class)
public class MyTest {
    //...
}

Removing @RunWith(PowerMockRunner.class) solved the issue for me.
