二、SSL運作原理(簡述)

1.Client透過HTTPS連到Server。 2.Server傳送Server Public Key給client。 3.Client產生後續傳輸資料需要用來加密\/解密用的Session Key,並以Server傳過來的Public Key加密後回傳給Server。 4.Server用Private Key解開Client以Public Key加密回傳的資料,以取得Session Key。 5.後續Client與Server間傳送資料就以此Session Key來做資料加密與解密的處理,處理的時間會比使用Server的Public Key與Private Key要快速許多。
