To quickly test if JCE with unlimited strength is activated on your java installation, run this:
import javax.crypto.Cipher; class JceTest { public static void main(String[] args) { try { int maxKeyLen = Cipher.getMaxAllowedKeyLength("AES"); System.out.printf("maxKeyLen=%d%n", maxKeyLen); if(maxKeyLen == 2147483647) { System.out.println("JCE with unlimited strength activated."); } else { System.out.println("JCE with unlimited strength NOT activated!"); } } catch (Exception e){ System.out.println("Sad world :("); } } }
