问题 I have installed laravel 5.7 in my system. I want to know that is it necessary to execute php artisan key:generate command? 回答1: php artisan key:generate This command sets the APP_KEY value in your .env file. If you create a project with composer it'll generated default with project. composer create-project laravel/laravel If you clone project using git clone some folder is ignored by git so you might not get env file as well as vendor folder. Therefore, they will have to manually enter php

问题 Here is my code snippet: int eValue = 79, t; int bitLength = 1024; // KeySize BigInteger e = new BigInteger(Integer.toString(eValue)); KeyPairGenerator kpg = KeyPairGenerator.getInstance("RSA"); kpg.initialize(bitLength); KeyPair kp = kpg.generateKeyPair(); KeyFactory kfactory = KeyFactory.getInstance("RSA"); RSAPublicKeySpec kspec = (RSAPublicKeySpec) kfactory.getKeySpec(kp.getPublic(), RSAPublicKeySpec.class); System.out.println("Byte Length is : " + kspec.getModulus().toByteArray().length)

Is Java security module KeyGenerator thread safe? If not then how to fix it?

问题 I have a concurrent encryption/decryption program in which multiple AES128 keys are randomly generated concurrently by invoking the following code (written in scala, the Java version should be fairly similar): private def AESKeyGen: KeyGenerator = { val keyGen = KeyGenerator.getInstance("AES") keyGen.init(128) keyGen } def generateKey: SecretKey = this.synchronized { AESKeyGen.generateKey() } each key is use to encrypt a fixed byte array, then decrypt it by using AESEncrypt and AESDecrypt

Generate RSA key pair in javascript, based on a password

由 梦想与她 提交于 2019-12-18 10:44:56
问题 As far as I understand, RSA keys are usually generated based on a (strong) random generator. Instead, I want to create them based on a password. Or rather on its hash, for example sha512(sha512(password+salt)+password+pepper) This needs to be done client side, in JavaScript. Would anyone know how to do this? Is there an easy JavaScript library that creates RSA key pairs deterministically, based on a given input? (Actually, I'm mentioning RSA but any secure asymmetrical encryption would

breeze and sql server triggers

问题 Breeze don't have a look of what's happened to data at server side when saving these data. Breeze team said you must re-query to have updated data. Actions done synchronously during this saving like sql triggers (expl. After Insert) may be considered because of these operations can transform entities during saving so they take place at client : this will be useful for new keys not generated by Breeze like multi-parts keys. I have difficult to work-around this problem. Help? UPDATE 1: If this

KeyPairGeneratorSpec replacement with KeyGenParameterSpec.Builder equivalents - Keystore operation failed

由 痞子三分冷 提交于 2019-12-09 13:11:17
问题 The following method is deprecated KeyPairGenerator generator = KeyPairGenerator.getInstance("RSA", "AndroidKeyStore"); KeyPairGeneratorSpec spec = new KeyPairGeneratorSpec.Builder(this) .setAlias(alias) .setSubject(new X500Principal("CN=Sample Name, O=Android Authority")) .setSerialNumber(BigInteger.ONE) .setStartDate(start.getTime()) .setEndDate(end.getTime()) .build(); generator.initialize(spec); The replacement I came upon looks like this KeyPairGenerator generator = KeyPairGenerator

How to generate rsa key pair in client side using angular2?

由 半腔热情 提交于 2019-12-08 14:25:29
I need to know how to generate 'rsa' key-pair on the client-side using angular2. I need to generate private/public key pair and save the private key into database and want to use public key inside the client side. How can I implement this? I found this https://www.npmjs.com/package/generate-rsa-keypair for generating key pair. But its for node? Can I implement it into my client side? If yes how? Is any other way to implement this? you must use https://github.com/juliangruber/keypair library then import it in angular component like import * as keypair from 'keypair'; and use library method

Why KeyPairGenerator.genKeyPair() so slow

由 二次信任 提交于 2019-12-07 18:38:49
问题 I have some Java code and when I run function KeyPairGenerator.genKayPair() it's work 40 seconds or more. How change this situation? If I run openssl req -x509 -nodes -days 365 -newkey rsa:4096 -keyout server.key -out cert.pem it's work 3 seconds. The slow code: KeyPairGenerator gen = KeyPairGenerator.getInstance("RSA"); SecureRandom random = new SecureRandom(); gen.initialize(4096, random); keyPair = gen.generateKeyPair(); PublicKey pubk = keyPair.getPublic(); PrivateKey prvk = keyPair
