若要暢遊網路世界,人們必須擁有電郵地址。要註冊成為YouTube、Facebook、Twitter、Reddit 用戶或使用其他線上服務,電郵都是您必填的資訊。電郵也是是我們辦理網銀業務、購物和進行商業交易的首要溝通媒介。因此,全球有超過一半的成年人是電子郵件用戶,人們也在電郵中提供了大量的個人資訊。 然而,電郵並不像大家所認知的那樣安全或私密。 電郵具有互通性,例如 Gmail 帳戶可以與 Yahoo 帳戶通信,Yahoo 帳戶可以與 ProtonMail 帳戶通信。 遺憾的是,這也意味著,無論您使用何種電郵服務,當您傳送訊息給隱私保護有待加強之電郵服務(如 Gmail)的用戶時,您的訊息都可能受制於其隱私政策。 所有主要電郵供應商都會提供一定程度的保護,以防止其用戶電郵被竊聽或篡改,但大多數的供應商都沒有提供最大程度的隱私與安全。 我們認為每個人都應享有電郵隱私和安全,意即沒有任何人可以存取您的電子郵件。因此,我們使用端到端加密 (E2EE) 保護您的電郵。 什麼是端到端加密電子郵件? 傳送電子郵件時,您的訊息會從一個伺服器行經另一個伺服器,直到抵達收件人的收件箱。 所有主要電郵供應商都使用 TLS(傳輸層安全協議),該協議會在電郵於伺服器間傳輸時加密路由,使您的訊息在傳輸過程中保持私密。 但使用 TLS 加密時,電郵並不是在到達收件人的裝置時才被解密,而是一旦到達電郵供應商的伺服器就會被解密。 這使得只使用TLS的電郵供應商能夠存取儲存在其伺服器上的所有訊息。 相比之下,端對端加密電子郵件的使用能夠確保除了目標收件人之外,任何人都無法存取該訊息,讓電郵更加安全。 端到端加密電郵在源頭(您的裝置)進行加密,並只有在到達端點(收件人的裝置)後才會進行解密。 由於只有對話的兩方可以存取和閱讀端到端加密電子郵件訊息,因此無論是您的電郵供應商、網際網路服務供應商或政府機構都無法存取所附資訊。 但是,端到端電郵加密僅在兩個人都使用 PGP 或使用相同的 E2EE 電郵服務(例如 ProtonMail )時才能發揮作用。 (我們使用 PGP 加密來確保 ProtonMail 的使用者可以與共用其公鑰的其他 PGP 使用者私密通信,即使那些使用者非 ProtonMail用戶。) 如果向使用僅採用 TLS 的電郵服務(例如 Gmail)用戶傳送電郵,您的電郵將受到其隱私策略之約束。並且,即使您使用 ProtonMail 帳戶傳送電郵,對方的電郵供應商還是可以存取您的郵件。 為了解決這些隱私問題,我們使用端到端加密和零存取加密,以保護您的電郵。 您還可以使用我們的「外部加密」功能向未使用 E2EE 電子郵件服務的使用者傳送端到端加密訊息 — 這些訊息會受到於 …
