问题 I have a test which runs great on my development MacBook Pro, but fails to run in continuous integration TeamCity server. The error is following: java.security.InvalidKeyException: Illegal key size at javax.crypto.Cipher.a(DashoA13*..) at javax.crypto.Cipher.init(DashoA13*..) at javax.crypto.Cipher.init(DashoA13*..) Both development box and TeamCity uses Java 1.6 and I use BouncyCastle library for the need of special AES encryption. The code is following: private byte[] aesEncryptedInfo

I know to get this to function correctly I install the JCE unlimited strength jars in the security folder. This is fine for me being the developer, I can install them. My question is since this app will be distributed, end users most likely will not have these policy files installed. Having the end user download these just to make the app function is not an attractive solution. Is there a way to make

问题 I understand that the keystore would usually hold private/public keys and the trust store only public keys (and represents the list of trusted parties you intend to communicate with). Well, that\'s my first assumption, so if that\'s not correct, I probably haven\'t started very well... I was interested though in understanding how / when you distinguish the stores when using keytool. So, far I\'ve created a keystore using keytool -import -alias bob -file bob.crt -keystore keystore.ks which
