Abstract

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.

Claims

1. A method for managing data storage using a network computer having one or more processor devices that perform actions, comprising:

employing the one or more processor devices to generate instruction set information that references at least a seed file that is installed on the network computer, wherein the seed file is determined from a plurality of seed files based on the instruction set information;

employing the one or more processor devices to extract a pass phrase from the seed file based on the instruction set information;

employing the one or more processor devices to generate an encryption key based on the instruction set information and the pass phrase that is extracted from the seed file;

employing the one or more processor devices to launch and execute an encryption engine, on the network computer, to encrypt data using the encryption key; and

employing the one or more processor devices to generate a secure bundle that includes a public key, the encrypted header information, and the encrypted data, wherein the secure bundle is presented to a provider of the data and the public key.

2. The method of claim 1, wherein the seed file is based on an offset value and a length value that are included in the instruction set information.

3. The method of claim 1, wherein the provider includes a user that provided the data and the public key or an application that provided the data and the public key.

4. The method of claim 1, further comprising generating header information that includes the instruction set information, wherein the header information is encrypted using the public key.

5. The method of claim 1, wherein the instruction set information includes one or more of an entity identifier, a platform identifier, or the public key.

6. The method of claim 1, further comprising:

generating a transport key based on the instruction set information; and

employing the encryption engine to employ the transport key to initially encrypt the data communicated between an application server and an application client; and

enabling the application server to generate one or more other transport keys for subsequent communication between the application server and the application client.

7. The method of claim 1, wherein generating the encryption key further comprises employing a signal provided by a sensor to introduce entropy in the generation of the encryption.

8. The method of claim 1, further comprising:

decrypting encrypted header information that is included in the secure bundle using a private key that corresponds to the public key that was used to encrypt the header information;

accessing the instruction set information that is included in the decrypted header information;

generating the encryption key based on the instruction set information;

decrypting the encrypted data that is included in the secure bundle using the encryption key, wherein the decrypted data is presented to the provider.

9. A system for managing data storage, comprising:

a network computer, comprising;

a transceiver that communicates over the network;

a memory that stores at least instructions; and

one or more processor devices that execute instructions that perform actions, including;

generating instruction set information that references at least a seed file that is installed on the network computer, wherein the seed file is determined from a plurality of seed files based on the instruction set information;

extracting a pass phrase from the seed file based on the instruction set information;

generating an encryption key based on the instruction set information and the pass phrase that is extracted from the seed file;
