摘要： A password reset disk is created using a private key/public key pair. The private key is stored on a removable computer-readable medium so that it can be removed and securely stored remote from the computer system on which it was created. The public key is stored on the computer system and used to maintain an encrypted copy of the current password to be stored on the computer system. If the user forgets a password, the user may insert the password reset disk into the computer system. The private key is retrieved from the password reset disk and the encrypted password is decrypted using the private key. If the decryption is successful, the user is allowed to set a new password. The password reset disk is effective even if the user password has been changed since the creation of the password reset disk.

摘要翻译： 使用私钥/公钥对创建密码重置磁盘。 私钥存储在可移动的计算机可读介质上，使得其可以被远离其创建的计算机系统并被安全地存储。 公钥存储在计算机系统上，用于维护要存储在计算机系统上的当前密码的加密副本。 如果用户忘记密码，用户可以将密码重置磁盘插入计算机系统。 从密码重置磁盘检索私钥，并使用私钥解密加密的密码。 如果解密成功，则允许用户设置新密码。 密码重置磁盘即使自创建密码重置磁盘以来已更改用户密码也是有效的。
