Я изо всех сил пытаюсь заставить шифрование PGP работать над проектом флаттера. Мой подход заключался в использовании шифрования пакета флаттера: ^ 4.0.0 (https://pub.dev/packages/encrypt)
Чтобы прочитать ключи, на которых я пробовал подход: https://gist.github.com/proteye/982d9991922276ccfb011dfc55443d74 который мне пришлось немного изменить, чтобы прочитать мои ключи
Тестовые ключи, которые я использую

Кому-нибудь удалось получить шифрование PGP работать с дротиком? Спасибо!
