السلام عليكم ورحمة الله وبركاته
عندى 3 أسئلة عن البروتوكول ده .. يا رب الاقى مساعدة عندكم ان شاء الله
معلش الاسئلة بالانجليزى
1-Are DSA and RSA independent encryption ciphers (cryptosystems) just as any other ciphers like AES, 3DES, ..etc and not just a asymmetric key generators that are used under other symmetric encryption algorithms ?
2- It is believed that RSA or DSA is used just for the authentication phase of the session and the rest of the session is just encrypted with symmetric algorithm (private key). Is that true ?
Because I read that SSH2 is a hybrid protocol which uses both symmetric and asymmetric encryption ciphers. Symmetric encryption for encrypting the bulk of the message and symmetric encryption for encrypting the symmetric key itself. Do they mean hybrid just for the authentication phase or for the entire session ?
3- Are the keys used to encrypt/decrypt is sent with each and every transmission of an encrypted packet, or the server/client establish the key first, then only the encrypted packet is sent ?
لو عرفت اجابة الاسئلة التلاتة دوول .. هيوضحولى كتير جدا عن البروتوكول ده وخصوصا انى قرأت كتير جدا عنه .. بس دايما التلات اسئلة دول مبلقيش ليهم اجابة
شكرا جزيلا
