摘要： Systems and methods for managing multiple keys for file encryption and decryption may provide an encrypted list of previously used keys. The list itself may be encrypted using a current key. To decrypt files that are encrypted in one or more of the previous keys, the list can be decrypted, and the appropriate previous key can be retrieved. To re-key files, an automated process can decrypt any files using previous keys and encrypt them using the current key. If a new current key is introduced, the prior current key can be used to decrypt the list of keys, the prior current key can be added to the list, and the list can be re-encrypted using the new current key.

摘要： A revocation determination service determines for a client whether a particular digital certificate as issued by a particular certificate authority (CA) has been revoked by such CA. In the service, an engine receives a query from the client, where the query identifies the particular certificate and the CA that issued the particular certificate. At least one provider is resident at the service, where each provider corresponds to a revocation information repository and represents the corresponding repository at the service, and connects to the corresponding repository. Each repository has revocation information from at least one CA. A configuration store includes a configuration information record corresponding to each provider resident at the service. Each configuration information record includes an identification of the provider and of each CA that the repository corresponding to such provider has revocation information for.
摘要翻译：撤销确定服务为客户确定由特定证书颁发机构（CA）发布的特定数字证书是否已由该CA撤销。在服务中，引擎从客户端接收查询，查询标识特定证书和发出特定证书的CA。至少一个提供者驻留在服务中，其中每个提供者对应于撤销信息存储库，并且表示服务处的相应仓库，并且连接到相应的仓库。每个存储库具有至少一个CA的撤销信息。配置存储包括与驻留在服务中的每个提供者相对应的配置信息记录。每个配置信息记录包括提供商和每个CA的标识，与该提供者对应的仓库具有撤销信息。

摘要： Methods and apparatuses are provided that can inform certain processes and/or even the user about the relative strength/weakness of cryptography services being used. In certain methods, for example, at least one cryptography service parameter threshold is established. The method further includes, selectively detecting a request for at least one cryptography service, and selectively performing at least one correctness detection action based on the requested cryptography service and the cryptography service parameter threshold. The cryptography service parameter threshold identifies acceptable/unacceptable cryptography algorithms, acceptable/unacceptable cryptography key size parameters, acceptable/unacceptable cryptography seed size parameters, and other like parameters that the requested cryptography service information can be compared with.
摘要翻译：提供了可以向某些进程和/或甚至用户通知正在使用的加密服务的相对强度/弱点的方法和装置。在某些方法中，例如，建立至少一个密码服务参数阈值。该方法还包括：选择性地检测对至少一个密码服务的请求，以及基于所请求的密码服务和密码服务参数阈值选择性地执行至少一个正确性检测动作。加密服务参数阈值识别可接受/不可接受的加密算法，可接受/不可接受的加密密钥大小参数，可接受/不可接受的加密种子大小参数以及可以与所请求的密码服务信息进行比较的其他类似参数。
