Issue with AES 256-Bit Encryption Key Size in C#

问题 I am trying to perform AES 256-bit CBC encryption in C#. I am using the sample key/iv strings from this page: http://pic.dhe.ibm.com/infocenter/initiate/v9r5/topic/com.ibm.einstall.doc/topics/t_einstall_GenerateAESkey.html However when I run the function below, I receive an error saying "Specified key is not a valid size for this algorithm." when attempting to set cipher.Key. I am able to use this key/iv combination in a node.js project, but I am attempting to port it to C# to no avail. What

AES-CMAC module for Node.js?

ε祈祈猫儿з 提交于 2021-02-11 17:23:46
问题 Is there a Node.js module that handles AES-CMAC (RFC 4493)? I've been searching around NPM, Google, and the like, but haven't found one. Somebody within my company built one that wraps Crypto++ as a C++ addon for Node.js, but unfortunately it doesn't build on Windows (depends on make ). Just looking for possible alternatives. This is similar to this other question, but I'm hoping for a Node.js specific implementation instead of a plain JavaScript one. Ideally something that makes use of Node

Convert number to ArrayBuffer

别等时光非礼了梦想. 提交于 2021-02-10 12:21:19
问题 I'm trying to decrypt data on the browser using the AES-CTR algo. The WebCrypto API requires the counter to be passed as a BufferSource. How do I convert the counter (a number) to the expected input (a byte array)? I'm using an all zero IV, so the counter starts at 0. Let's say I'm trying to decrypt data where counter = 445566. How do I convert 445566 into an ArrayBuffer? const key = // retrieve decryption key const encrypted = // retrieve encrypted data const iv = new ArrayBuffer(16) // iv

问题 I have a php file which is as follow: $encryption_encoded_key = 'c7e1wJFz+PBwQix80D1MbIwwOmOceZOzFGoidzDkF5g='; function my_encrypt($data, $key) { $encryption_key = base64_decode($key); $iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('aes-256-cfb')); $encrypted = openssl_encrypt($data, 'aes-256-cfb', $encryption_key, 1, $iv); // The $iv is just as important as the key for decrypting, so save it with encrypted data using a unique separator (::) return base64_encode($encrypted . '::'

问题 I am trying to write a python code which has same functionarities of AES_ENCRYPT and AES_DECRYPT of MySQL. https://dev.mysql.com/doc/refman/5.6/ja/encryption-functions.html I want to encrypt and decrypt data between MySQL and Python. For example, I want to decrypt data by python, which is encrypted by AES_ENCRYPT of MySQL. And I want to decrypt data by AES_DECRYPT of MySQL, which is encrypted by Python vice versa. I found a example of AES_ENCRYPT in Python. https://www.maykinmedia.nl/blog
