User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.1.4) Gecko/20091016 Firefox/3.5.4 Build Identifier: 4.3 RTM (with NSPR 4.8 and NSS 3.12.4) SunJCE returns block sizes for AES (16), DES (8), DESede (8), and RC2 (8) before the Cipher is initialized. The Mozilla-JSS JCE provider returns 0 until the Cipher is initialized. Sample code. Pass an argument like "AES/CBC/NoPadding" on the command line. import javax.crypto.Cipher; import org.mozilla.jss.CryptoManager; public class BlockSize { public static void main(String[] args) throws Exception { String cipherName = args[0]; CryptoManager.InitializationValues initializationValues = new CryptoManager.InitializationValues("."); initializationValues.fipsMode = CryptoManager.InitializationValues.FIPSMode.DISABLED; CryptoManager.initialize(initializationValues); int blockSizeSunJce = getBlockSize(cipherName, "SunJCE"); int blockSizeMozillaJss = getBlockSize(cipherName, "Mozilla-JSS"); System.out.println("SunJCE: " + blockSizeSunJce); System.out.println("Mozilla-JSS: " + blockSizeMozillaJss); } public static int getBlockSize(String cipherName, String provider) throws Exception { Cipher cipher = Cipher.getInstance(cipherName, provider); return cipher.getBlockSize(); } } Reproducible: Always
