Secure storage for shared documents
Embodiments are directed towards managing data storage for secure storage of shared documents. A user or an application may provide data destined for encryption and a public key. Instruction set information that references at least a seed file that may be installed on the network computer may be generated. An encryption key based on the instruction set information may be generated. Header information that includes the instruction set may be generated. And, the header information may be encrypted using the public key. A secure bundle that includes the public key, the encrypted header information, and the encrypted data may be generated and provided to the user that provided the data and the public key or the application that provided the data and the public key. Decrypting the data included in the secure bundle the above actions are generally performed in reverse.

8. The system of claim 7 , further comprising providing the secure bundle to either the party that provided the one or more portions of the file data and the one or more public keys or an application that provided at least the file data and the one or more public keys.
9. The system of claim 7 , wherein the network computer performs further actions, comprising: launching and executing an encryption engine, on the network computer, to encrypt the file data using the one or more encryption keys.
10. The system of claim 7 , wherein the one or more encrypted headers, further comprise one more of seed values, cache values, and metadata, wherein the metadata includes one or more of check sum values, file size information, creation date, the first collection of the one or more public keys, or the identifier.
11. The system of claim 7 , wherein the seed file is based on an offset value and a length value that are included in the instruction set information.
12. The system of claim 7 , wherein the instruction set information includes one or more of an entity identifier, a platform identifier, or the public key.
13. A processor readable non-transitory storage media that includes instructions for managing data storage, wherein execution of the instructions by a hardware processor performs actions on a secure bundle data structure, comprising:
