cryptojs

I've been trying to decrypt an ArrayBuffer object using CryptoJS, but so far it always returns a blank WordArray. The files (images) are encrypted in an iOS and Android app, sent to a server, and downloaded in this web app to be decrypted and displayed. The iOS and Android apps are able to decrypt the files without problems, so there's nothing wrong with the encryption process. The files are downloaded with an XMLHttpRequest with responseType set to arraybuffer . Here's my code so far: // Decrypt a Base64 encrypted string (this works perfectly) String.prototype.aesDecrypt = function(key) { var

I am trying to create a simple webpage with the goal to send and encrypted message to the server (which will create a file with that content), then a link is created and the user who receive the link provided will be able to see the encrypted value (since it provides the name of the file and the key). The message is encrypted using CryptoJS AES, and the result is Base64 encoded to be decoded after that, only the Base64 of the encrypted message and the encrypted message is sent to the server nothing else, and this is done using Javascript. My question here is. I have a message, let say "Hello

I'm trying to replicate the Java code in JavaScript. below is my Java code: public static String encrypt(String input) final byte[] SALT= { (byte) 0x21, (byte) 0x21, (byte) 0xF0, (byte) 0x55, (byte) 0xC3, (byte) 0x9F, (byte) 0x5A, (byte) 0x75 }; final int ITERATION_COUNT = 31; { if (input == null) { throw new IllegalArgumentException(); } try { KeySpec keySpec = new PBEKeySpec(null, SALT, ITERATION_COUNT); AlgorithmParameterSpec paramSpec = new PBEParameterSpec(SALT, ITERATION_COUNT); SecretKey key = SecretKeyFactory.getInstance("PBEWithMD5AndDES").generateSecret(keySpec); Cipher ecipher =

I encrypt some data using AES in a server application, which is written in C#. I use a predefined key (32 bytes) and IV (16 bytes), for instance... Key: 81fe1681..6a451c1c IV: e83c..ae76 This is my C# code I use to encrypt the data: async Task<byte[]> Encrypt(string privateKey, string pin, byte[] data) { using (var sha = SHA256.Create()) { byte[] keyHash = sha.ComputeHash(Encoding.UTF8.GetBytes($"{privateKey}")); byte[] pinHash = sha.ComputeHash(Encoding.UTF8.GetBytes($"{pin}")); using (Aes aes = Aes.Create()) { byte[] key = keyHash.Slice(0, aes.Key.Length); byte[] iv = pinHash.Slice(0, aes.IV

I am working with JavaScript to generate File HASH VALUE for unique file values. Kindly check the below code for the Hash Generation Mechanism Which works good. <script type="text/javascript"> // Reference: https://code.google.com/p/crypto-js/#MD5 function handleFileSelect(evt) { var files = evt.target.files; // FileList object // Loop through the FileList and render image files as thumbnails. for (var i = 0, f; f = files[i]; i++) { var reader = new FileReader(); // Closure to capture the file information. reader.onload = (function(theFile) { return function(e) { var span = document

Here's what I have so far: function sha256(stringToSign, secretKey) { return CryptoJS.HmacSHA256(stringToSign, secretKey); } function getAmazonItemInfo(barcode) { var parameters = "Service=AWSECommerceService&" + "AWSAccessKeyId=" + appSettings.amazon.accessKey + "&" + "Operation=ItemLookup&" + "ItemId=" + barcode + "&Timestamp=" + Date.now().toString(); var stringToSign = "GET\n" + "webservices.amazon.com\n" + "/onca/xml\n" + parameters; var signature = "&Signature=" + encodeURIComponent(sha256(stringToSign, appSettings.amazon.secretKey)); var amazonUrl = "http://webservices.amazon.com/onca
