问题 I am creating a method to generate a key pair.I need to secure the private key with a password.My code works fine except that it gives me java.security.InvalidKeyException: Illegal key size or default parameters error. When i searched the cause of the error,it says to replace the policy jars in jre/lib/security folder with unlimited access files for the same.I have jdk7 installed and i downloaded the policy files and replaced that the lib/security folder.But the error remains the same.Here is

JSch SFTP security with session.setConfig(“StrictHostKeyChecking”, “no”);

由 柔情痞子 提交于 2019-12-17 09:57:49
问题 I use JSch with private key to FTP file jsch.addIdentity(privatekeyfile); Session session = jsch.getSession( "user", "domain.com" ,22); session.setConfig("StrictHostKeyChecking", "no"); Line 3 is in question. Without this line, JSch does not work. My question is: Will line 3 make SFTP transfer insecure? 回答1: Disabling the StrictHostKeyChecking option will make the connection less secure than having the option enabled, because it will let you connect to remote servers without verifying their

How to encrypt serializable objects

由 痴心易碎 提交于 2019-12-14 03:06:25
问题 I'm currently working on a client-server application in Java. Due to the requirements for the application I need to encrypt the traffic between client and server and decided to use a hybrid encryption approach where the server generates a public/private RSA key pair and the client generates an AES session key which will be encrypted using the RSA public key. As I'm completely new to encryption in Java I didn't start implementing it directly into my application so I don't crash anything. I set

Generate KeyPair with RandomSecure

由 别来无恙 提交于 2019-12-11 01:18:56
问题 Is there anyway I can generate always the same private key? I tired to initialize KeyPairGenerator with a RandomSecure object which uses the same seed : private PrivateKey getPrivateKey(String seed) { try { SecureRandom sr = new SecureRandom(seed.getBytes()); KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA"); keyGen.initialize(1024, sr); KeyPair keyPair = keyGen.generateKeyPair(); return keyPair.getPrivate(); } catch (NoSuchAlgorithmException e) { System.out.println("Failed to

AWS EC2 Key Pair setup

由 雨燕双飞 提交于 2019-12-10 11:45:16
问题 I'm trying to setup my AWS EC2 Instance with a Key Pair that I just created. The original instance was already setup without a key pair, so I'm trying to Launch a new Instance and set the Key Pair during that process. AWS docs instruct to "Specify the new key pair that you created" after I select the AMI, but I do not see anywhere that I can do this during the creation process. So, either I'm really clueless or something is not showing up correctly in the AWS creation steps (probably the
