  • Method Details

    • isUnlimitedStrength

      public static boolean isUnlimitedStrength()
      Checks if unlimited cryptographic strength is supported. If not download the appropriate jurisdiction policy files for your Java edition:

      JCE Unlimited Strength Jurisdiction Policy Files for Java 7

      JCE Unlimited Strength Jurisdiction Policy Files for Java 8

      Returns:
      true if unlimited cryptographic strength is supported, false if not.

    • isSupported

      public static boolean isSupported(Algorithm alg)
      Checks if the specified JOSE algorithm is supported by the default system JCA provider(s).
      Parameters:
      alg - The JOSE algorithm. Must not be null.
      Returns:
      true if the JOSE algorithm is supported, else false.

    • isSupported

      public static boolean isSupported(Algorithm alg, Provider provider)
