Hi, I am trying to decrypt a message using AES128 in ECB mode, and not CBC mode. The data I am trying to decrypt is sent to my B4J as AES-128 in ECB mode, and that data I have put into a string called 'dataToDecrypt' in my code below. When I run the following code I get the following... that encrypted the string that was sent kg.Initialize("AES") kg.KeyFromBytes(Key.GetBytes("UTF8")) C.Initialize("AES/ECB/NoPadding") ' not 100% sure...

This library offers a simple, secure, and powerful solution for encrypting and decrypting sensitive data (emails, addresses, phone numbers, etc.) directly from a B4J application, leveraging the robustness of the Python cryptography library. The Lib exposes three main methods: GetKey: Generates a secure Fernet key (AES 128 + HMAC) Encrypt: Encrypts a text string with this key Decrypt...) Benefits: Strong security thanks to Fernet (AES + HMAC) Easy integration into any B4J app No...
