Notes®如何使用公用金鑰和專用金鑰加密和簽章郵件
HCL Notes® uses a public and private key set to encrypt and decrypt data, as well as to validate digital signatures. The public and private key in a set are mathematically related to each other and are unique to your User ID. Your public key is stored in your Notes® certificate. Your certificate is stored in your User ID and the HCL Domino® Directory. Your private key is stored only in your User ID.
人們可以使用位於 Domino ®目錄中的您的憑證的公鑰來加密他們傳送給您的資料。當您收到加密資料時，您的使用者 ID 中的私鑰會解密資料。
公鑰和私鑰有哪些不同類型？
There are Notes® public and private keys and Internet certificate public keys with their corresponding private keys. The Notes® keys are used to encrypt data relayed between Notes® users. The Internet keys are used to send and receive S/MIME mail messages and to encrypt TLS transactions between Notes® and Internet servers.
When your User ID is created, it automatically has Notes® public and private keys attached to it. Your Domino® administrator can add Internet private keys during registration, or you can request them at a later time.
您可以透過選擇來查看您的證書 > 安全 > 使用者安全（Macintosh OS X 使用者：注意事項 > 安全 > 使用者安全），點擊，然後在下拉清單中選擇“所有證書”。您可以查看所有憑證和已儲存的金鑰（您已取代但仍需要解密資料的金鑰）。
公鑰和私鑰集如何運作？
任何想要向您發送加密郵件或對您進行身份驗證的人都可以存取您的公鑰。
您收到的郵件使用您的公鑰加密，並使用您的私鑰解密。您的郵件資訊使用您的私鑰進行數位簽名，並使用您的公鑰進行驗證。使用您的公鑰加密的任何內容都必須使用您的私鑰解密，反之亦然。但是，您的私鑰是保密的。儘管你的公鑰可以被訪問，但你的私鑰卻不能。
