摘要： In accordance with one or more aspects, a key protector for a storage volume is created by generating an intermediate key and protecting, based at least in part on a public/private key pair, the intermediate key. A volume master key for encrypting and decrypting one or more volume encryption keys that are used to encrypt the storage volume can be encrypted in different manners, including being encrypted based at least in part on the intermediate key. A key protector for the storage volume is stored that includes both the encrypted volume master key and information indicating how to obtain the intermediate key. Subsequently, the key protector can be accessed and, based at least in part on a private key of the entity associated with the key protector, the intermediate key can be decrypted. The intermediate key can then be used to decrypt the volume master key.

摘要： A portable secure data file includes an encrypted data portion and a metadata portion. When a request associated with a current user of a device to access a portable secure data file is received, one or more records in the metadata portion are accessed to determine whether the current user is permitted to access the file data in the encrypted data portion. If a record indicates the user is permitted to access the file data, a content encryption key in that record is used to decrypt the encrypted data portion.

摘要： In one embodiment, a virtual machine replication system may test a replica data set while continuing to replicate a primary data set. A data storage 250 may store a replica data set for a replica virtual machine 302 to back up a primary data set for a primary virtual machine 304. The data storage 250 may preserve a test point in time 322 in the replica data set using a test differencing disk 344. A processor 220 may execute a test virtual machine 342 that performs a test operation on the test point in time 322 while the replica data set continues to replicate the primary data set.

摘要： A method described herein includes at a computing device, receiving, over a network connection, a data packet from an external source, wherein the data packet comprises a compressed abstract syntax tree (AST)-based representation of source code written in a scripting language. The method further includes decompressing the compressed AST-based representation of the source code to generate a decompressed AST. The method also includes causing at least one processor on the computing device to execute at least one instruction represented in the decompressed AST subsequent to the compressed AST-based representation of the source code being decompressed.
