Итак, я пытаюсь написать приложение, которое позволяет пользователю шифровать и дешифровать файлы, используя AES и пароль по своему выбору. Однако проблема в том, что FileStream не позволяет мне копировать зашифрованное сообщение (которое пользователь создает в виде документа Word или блокнота), а затем указывает программе, где они его сохранили.
Проблема, с которой я столкнулся, FileStream не может записать зашифрованное содержимое в файл, говоря, что серьезность
