Hushmail... خدمة البريد الآمنة

يُقدم Hushmail خدمة بريد مجانية على موقع الويب تسمح بإستقبال وإرسال الرسائل بأمان عالي حيث تقوم بتشفير الرسائل ومرفقاتها بإستخدام خوارزميات تُؤمّن للمستخدم مستوى أعلى من الأمان والسرية بحيث لايمكن الوصول للرسائل حتى من الشركة نفسها.




يُمّكن Hushmail المستخدم من إرسال ايميلات مشفرة بكلمة سر أو سؤال سري، هكذا لن يتمكن أحد من الدخول للإيميل إلا ومعه الإجابة على السؤال، أو كلمة الفك التي اختارها المرسل ويبعثها للمستقبِل لاحقا، إما عن طريق ايميل آخر او مباشرة او على الهاتف.
ملاحظات:

1- يجب عليك الدخول إلى حسابك على Hushmail مرة على الأقل كل ثلاثة أسابيع و إلا ألغي.
2- تعمل منظومة السرية في  Hushmail إذا استخدمت في التراسل مع مستخدمي Hushmail آخرين فقط ، فإذا تم استخدامها للتراسُل مع مستخدمين خدمة بريدية أخرى، مثل Hotmail مثلا، فإن منظومة الأمن كلها تنعدم.
