How to decrypt with CryptoJS using AES?

阅读更多关于 How to decrypt with CryptoJS using AES?

问题 As the question suggests, I can't seem to get a decrypted value correctly using the required options (AES, ECB Mode & PKCS7). I'm encrypting as below: var ENC_KEY = "bXlrZXk="; //"mykey" var encrypted = CryptoJS.AES.encrypt("hello", CryptoJS.enc.Base64.parse(ENC_KEY), { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 }); console.log('encrypted: ' + encrypted); which works as expected and outputs the encrypted value I expect however when I decrypt this using the below, I end up with an

Securely encrypt integers (up to 2^48) into the shortest possible URL-safe string

阅读更多关于 Securely encrypt integers (up to 2^48) into the shortest possible URL-safe string

问题 In my Django application I have hierarchical URL structure: webpage.com/property/PK/sub-property/PK/ etc... I do not want to expose primary keys and create a vulnerability. Therefore I am encrypting all PKs into strings in all templates and URLs. This is done by the wonderful library django-encrypted-id written by this SO user. However, the library supports up to 2^64 long integers and produces 24 characters output (22 + 2 padding). This results in huge URLs in my nested structure. Therefore,

Generate AES key on node

阅读更多关于 Generate AES key on node

问题 I'm dealing with a legacy application that uses a custom protocol to cipher communication. Random AES keys are generated in legacy Java app like this: keygen = KeyGenerator.getInstance("AES"); keygen.init(128); keygen.generateKey().getEncoded(); I've been looking for solutions on crypto with no luck. How can I generate this key on nodejs? 回答1: That code probably does not do as much as you think. It simply generates 16 (128 / 8) secure random bytes, then wraps a key object around it. So with

问题 I try to do crypto on node.js but badly I fail to have the same result than online sites. I want to encrypt some binary data with a binary key. I use the tutorial on nodejs site but I have a different result from my reference data set. My reference data set is validated with java code, with C code and with two online site : http://aes.online-domain-tools.com/ and https://www.hanewin.net/encrypt/aes/aes-test.htm Have you an idea how to encrypt the same way that those sites? I guess it can be

Decrypt MCRYPT_RIJNDAEL_256 with 32-byte initialization vectors with PyCrypto

阅读更多关于 Decrypt MCRYPT_RIJNDAEL_256 with 32-byte initialization vectors with PyCrypto

问题 I have data that was encrypted in PHP as follows: mcrypt_encrypt(MCRYPT_RIJNDAEL_256, SECRET, $data, MCRYPT_MODE_CBC, $iv) I need to decrypt this data in a Python 3 application. I am trying to use PyCrypto but I am open to other libraries. I expect the following to work: decryptor = AES.new(key, mode, IV=IV) plain = decryptor.decrypt(ciphertext) My initialization vector is 32 bytes, and the following exception is thrown: ValueError: IV must be 16 bytes long How can I set PyCrypto to use a 32

Inplace AES CBC/ECB mode encrypting/decrypting using Crypto++

问题 Is it explicitly allowed to use the same buffer for plaintext/ciphertext when performing AES encryption/decryption in CBC and ECB modes using Crypto++ (assuming the buffer size is sufficient to accomodate the encrypted data) as in the following code: #include <cstdio> #include <cassert> #include "cryptopp\rsa.h" #include "cryptopp\rijndael.h" #include "cryptopp\modes.h" int main() { using namespace CryptoPP; byte key[32], iv[Rijndael::BLOCKSIZE]; char testdata[] = "Crypto++ Test"; // any data

Symmetric Encryption between .NET and Java

问题 I am using a 3rd party platform to create a landing page, it is a business requirement that I use this particular platform. On their page I can encrypt data and send it to my server through a request parameter when calling a resource on my site. This is done through an AES Symmetric Encryption. I need to specify a password, salt (which must be a hex value) and an initialization vector (but be 16 characters). Their backend is a .NET platform. I know this because if I specify an IV longer than

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

阅读更多关于 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
