Це означає, що якщо ваш приватний ключ для розшифрування буде скомпрометовано, а хтось заздалегідь зібрав ваші повідомлення під час передачі, він зможе розшифрувати та прочитати їх, використовуючи зламаний ключ. Зверніть увагу, що пряма секретність підвищує рівень безпеки лише в тому разі, якщо ви видаляєте повідомлення. Інакше, якщо хтось отримує доступ до ваших ключів розшифрування, він зазвичай також має доступ до всіх ваших невидалених повідомлень і навіть не потребує розшифровувати заздалегідь перехоплені дані.</p>
