Python Code: from Crypto.Random import get_random_bytes from Crypto.Cipher import AES from Crypto.Util.Padding import pad import base64 def encrypt_string(input_string, key_base64, str_iv): try: key = key_base64.encode('utf-8') if str_iv: iv = base64.b64decode(str_iv) else: iv = get_random_bytes(16) cipher = AES.new(key, AES.MODE_CBC, iv) padded_data =…
I am trying to encrypt my password in the frontend (javascript)before I send it to the backend (fastapi, python) Although many Google searches said crypto can be used, I saw that it works only in the nodejs environment and not…
I am trying to compile the nwipe project from the following GitHub repository: https://github.com/Knogle/nwipe/tree/master. The compilation process completes successfully on a Fedora system, but fails on an Ubuntu machine with the same version of OpenSSL (greater than 3.0.2), which should…
Consider this code a web site may use for verifying a password $givenPassword = /*whatever was entered*/; //look up $username, $encryptedPassword if (password_verify($givenPassword, $encryptedPassword)) { //log user in and do good things } Suppose a hacker has stolen the database…
I'm trying to get the data decoded using Node native methods, I search how to achieve this but it get invalid iv initialization or Unsupported state or unable to authenticate data trying differents iv aes-128 -> 16 bytes it results…
I need to convert an Rijndael encryption function from C# to Node. But I cannot match the result, even with the same Key, IV, Mode and Block Size. What am I doing wrong? C# MRE: using System.Security.Cryptography; byte[] encrypted; using…
I have an encryption function in C# and i wish to copy it to dart: C# (The part of code i cant reproduce in dart): private RijndaelManaged myRijndael = new RijndaelManaged(); public ClsCrypto(string strPlainText) { string strIV = "$@A@B@_3CP$Y$T2M"; myRijndael.IV…
I created a valid pdf with a single blank page and an existing text field, everything is fine: I can edit the pdf and save it, everything is fine. I tested the pdf with tools for validation, the pdf is…
