Decrypt AES/CBC/PKCS5Padding with CryptoJS

江枫思渺然 提交于 2019-12-03 21:54:13
I generate 128bit AES/CBC/PKCS5Padding key using Java javax.crypto API. Here is the algorithm that I use: public static String encryptAES(String data, String secretKey) { try { byte[] secretKeys = Hashing.sha1().hashString(secretKey, Charsets.UTF_8) .toString().substring(0, 16) .getBytes(Charsets.UTF_8); final SecretKey secret = new SecretKeySpec(secretKeys, "AES"); final Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding"); cipher.init(Cipher.ENCRYPT_MODE, secret); final AlgorithmParameters params = cipher.getParameters(); final byte[] iv = params.getParameterSpec(IvParameterSpec.class)

How to sign a JWT with a private key (pem) in CryptoJS?

问题 I am trying to create a signed JWT in postman with the following code function base64url(source) { // Encode in classical base64 encodedSource = CryptoJS.enc.Base64.stringify(source); // Remove padding equal characters encodedSource = encodedSource.replace(/=+$/, ''); // Replace characters according to base64url specifications encodedSource = encodedSource.replace(/\+/g, '-'); encodedSource = encodedSource.replace(/\//g, '_'); return encodedSource; } function addIAT(request) { var iat = Math

How can I encrypt/decrypt arbitrary binary files using Javascript in the browser?

╄→尐↘猪︶ㄣ 提交于 2019-12-03 20:48:51
I need to let users load files from their system, encrypt them on-the-fly and upload to the server and do the opposite thing (download files from the server, decrypt on the fly and let the user save them locally). The exact crypto method is not very important although AES is preferred. Links like Encryption / decryption of binary data in the browser just tell you "use CryptoJS" but I was unable to find any actually working samples. All samples I found focus on dealing with strings while in binary data you can easily find invalid Unicode sequences. Is there any working sample I can test which

问题 I have user sign in form. It has about 10 inputs. I want to save that user, random generate password and hash and salt it and save it. How to achieve that? I couldn't find any good tutorial for using Crypto.js in meteor. I always stumble upon account-password package. 回答1: accounts-password actually takes care of this for you. I wish the documentation of the implementation details was better, but you can see an overview here. Passwords are verified by examining hashes, so only a hashed

CryptoJS and key/IV length

无人久伴 提交于 2019-12-03 13:33:35
问题 I have question about AES key and IV length. First of all, if, for example, I'm using drugs OpenSSL extension and openssl_encrypt() method, I can clearly see that key for 256-bit AES should be 32 bytes, and IV throws warning if it's different than 16 bytes. I can understand that, and everything is fine. However, in CryptoJS library the key and IV length is frustrating. This is some example: var text = "test", key = "us5N0PxHAWuIgb0/Qc2sh5OdWBbXGady", iv = "zAvR2NI87bBx746n"; key = CryptoJS

Closed . This question needs details or clarity. It is not currently accepting answers. Learn more . Want to improve this question? Add details and clarify the problem by editing this post . I am trying to encrypt a data in java and decrypt the same in javascript. There is already a similar question in SO but it does not work for me. My question is - Encrypted Text given by Java code is not getting decrypted by Javascript. I have hardcoded the the encrypted text and key in my JS below. P.S. I know decryption on the UI is of no use as Key will be visible and any user can decode the code. But my

How to use CryptoJS with Angular 4

北城以北 提交于 2019-12-03 01:57:35
When I was not using Angular 4, I would just put the script tags for the library. Even when I put the script tags in the index.html file it is not recognizing CryptoJS . Is there a way to use the library or a Angular equivalent? Install using NPM and import below statement in you component file. npm install crypto-js import * as crypto from 'crypto-js'; now you can use crypto in your component file. Use following command to install cryptoJS npm install crypto-js --save You can then build a AESEncryptDecryptService service. import { Injectable } from '@angular/core'; import * as CryptoJS from
