не совсем верное условие ,ключ длиной 512 пройдет
корректнее if 32 <= key_length <= 448 and key_length % 8 == 0:

для выбора режима шифрования используйте match/case и Enum

В работе была создана Гибридная криптосистема, совмещающая в себе два протокола RSA и Blowfish. Ассиметричным алгоритмом (RSA) был получен ключ для симметричного шифрования (Blowfish).
Папка keys - для хранения созданных в процессе шифрования ключей. Папка texts - для хранения изначального, зашифрованного и расшифрованного текстов
