cryptojs

问题 I want to decrypt a string that has been encrypted with openssl on the server like this: openssl enc -e -aes-256-cbc -pbkdf2 -a -S 0123456789ABCDEF -A -k mypassword Note this is done providing only a salt and password, and openssl should handle key and IV automatically. Am I too optimistic that this can happen when the browser decrypts too? If at all possible, I want to do it with only those encryption settings, or the bare minimum of increased complexity. In the browser, I'm trying to

问题 The scenario is that I have a JS script that creates a HMAC for a user provided input and I want to compute the same HMAC for the same input using python. To make things clearer, consider the following JS and Python code snippets. Javascript <script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/crypto-js.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/hmac-sha256.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs

问题 I am trying to encrypt/decrypt the below data using crypto-js and getting unexpected results. Library: https://cdnjs.cloudflare.com/ajax/libs/crypto-js/4.0.0/crypto-js.min.js function encryptByAESECB(message, key) { var keyHex = CryptoJS.enc.Utf8.parse(key); var encrypted = CryptoJS.AES.encrypt(message, keyHex, { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.NoPadding }); return encrypted.toString(); } function decryptByAESECB(ciphertext, key) { var keyHex = CryptoJS.enc.Utf8.parse(key); //

问题 I have code in java for encryption public String encrypt() throws Exception { String data = "Hello World"; String secretKey = "j3u8ue8xmrhsth59"; byte[] keyValue = secretKey.getBytes(); Key key = new SecretKeySpec(keyValue, "AES"); Cipher c = Cipher.getInstance("AES"); c.init(Cipher.ENCRYPT_MODE, key); byte[] encVal = c.doFinal(StringUtils.getBytesUtf8(data)); String encryptedValue = Base64.encodeBase64String(encVal); return encryptedValue; } It returns same value ( eg5pK6F867tyDhBdfRkJuA== )

问题 I understand that there exist other libraries which make my life easier to work with JWT (in node.js). In this case, I am using "crypto-js" to learn JWT in a manual way. The following gives me the token: var header = { "alg": "HS256", "typ": "JWT" }; var wordArrayHeader = CryptoJS.enc.Utf8.parse(JSON.stringify(header)); var base64Header = CryptoJS.enc.Base64.stringify(wordArrayHeader); var payload = { "sub": "1234567890", "name": "John Doe", "admin": true }; var wordArrayPayload = CryptoJS

问题 I am trying to get the md5sum of a tar file to produce the same value when using the md5sum linux command and CryptoJS's MD5 method. In JavaScript I do (after a file has been put in an HTML form): var reader = new FileReader(); reader.onloadend = function () { text = (reader.result); } reader.readAsBinaryString(document.getElementById("firmware_firmware").files[0]); var hash = CryptoJS.MD5(text); hash.toString(); In Linux I do: md5sum name_of_file.tar Currently these two produce different

问题 I know 3DES and MD5 are insecure. I will work on replacing them once I have it working again, I have a mobile app that is using 3DES with an MD5 of a key as a SECRET KEY to talk to a PHP Application. Now this code worked perfectly on PHP 5.3 (this is an example I have generated) mcrypt_decrypt( MCRYPT_3DES, md5( utf8_encode( "MobileAppSecureKey" ), true ), base64_decode("bkCfcseIt/TPsgNCdyX9fv2/4MjOJdaPXakNNbxQT3n6tXHa5bDoXojQ3g7jPLCu+wjwD0guQzw3hCFUSVx47PmDNHASk7g/kJ4K4tX0VGI="), MCRYPT_MODE

问题 Hey I have such Javascript code CryptoJS.algo.AES.keySize = 32, CryptoJS.algo.EvpKDF.cfg.iterations = 1e4, CryptoJS.algo.EvpKDF.cfg.keySize = 32; var decrypted = CryptoJS.AES.decrypt(message, passphrase); And I need to create an analog using Python (I'm trying to use pycryptodome) But I have several questions: Have can I get key and iv from passphrase? How should reflect all these (CryptoJS.algo.AES.keySize = 32, CryptoJS.algo.EvpKDF.cfg.iterations = 1e4, CryptoJS.algo.EvpKDF.cfg.keySize = 32
