I'm able to decrypt AES encrypted message with Ruby like this:  require 'openssl' require 'base64'  data = "IYkyGxYaNgHpnZWgwILMalVFmLWFgTCHCZL9263NOcfSo5lBjAzOZAtF5bF++R0Bi+9c9E+p3VEr/xvj4oABtRWVJ2wlWzLbYC2rKFk5iapFhb7uZCUpO4...
We've got a Silent Login service written in Coldfusion9 that accepts encrypted strings from external systems and then decrypts based on an agreed Algorithm/Encoding setup. This has worked without issue for years now from systems running ASP/JAVA/...
After watching a YouTube video on the Diffie-Hellman Key Exchange, I wanted to try an implementation in JavaScript (Atwood's law).  I sketched up an cipher on Node.js with the following rules:   Step 1: Client and server agree on a shared key:...
I am trying to encrypt in Javascript with CryptoJS and decrypt in PHP. The JS code is:  var salt = CryptoJS.lib.WordArray.random(128/8);  var key256Bits500Iterations = CryptoJS.PBKDF2("Secret Passphrase", salt, { keySize: 256/32, iterations:...
Hi so lets assume that client-side has a key that is not transfered via the same channel as the encrypted data.   What I am trying to accomplish is to decrypt the result of Stanford Javascript Crypto Library (sjcl) in ruby. or for a generalisation in...
Some background information, you can skip this part for the actual question  this is my third question about this topic here at stackoverflow. To be complete, these are the other questions AES with crypt-js and PyCrypto and Match AES de/encryption in...
I'm attempting to write a web app that uses AES encryption over AJAX to interact with a Java backend.  I've spent some time looking for and testing libraries and none of them have proven fruitful.  I have Java <-> PHP working correctly...
In trying to understand the Node.js Crypto API, I have been trying to match code to the equivalent OpenSSL enc command line (line breaks inserted for readability) which is piped through xxd for hex display.  $ echo -n "The quick brown fox jumps o...
I'm new to cryptography and I'm building some test applications to try and understand the basics of it. I'm not trying to build the algorithms from scratch but I'm trying to make two different AES-256 implementation talk to each other...
I try to implement a communication between   crypto-js (a javascript crypto library)  and pycrypto (a python crypto library)   On the python server side I encrypt a string with an iv and a passphrase and send the iv with the encrypted text base64 enc...
