Abstract
Methods and systems for encrypting and decrypting data are described. In one embodiment, a client computing system sends to a server computing system over a network a first network request to perform multiple operations such as a lease operation and a fetch operation. In response, the server computing system performs the operations. Subsequently, the client computing system can send subsequent network requests to write re-encrypted data and to relinquish the lease. The subsequent network requests may also be single network requests that perform lease operations, as well as other operations, such as operations for block alignment purposes. The client computing system can send an actual end of file when relinquishing the lease so that the server computing system can handle a remainder of data that is used for subsequently decrypting the re-encrypted data.
