CloudBlackbox package of SecureBlackbox®

Secure data storage in DropBox, Google, Amazon S3 and Microsoft Azure

With CloudBlackbox you get a simple method to secure, transfer and store your data to and from the cloud storage. Unlike APIs provided by cloud services themselves CloudBlackbox has built-in sophisticated encryption and compression mechanisms which reduces storage and transfer costs by compressing the data, and also lets you keep the data encrypted using both symmetric algorithms and X.509 certificates.

You can store the data using the uniform access mechanism to any of supported cloud services, with encryption and authentication being applied transparently. Currently supported cloud storages include Amazon Web Services (S3), Microsoft Azure, Google Drive, OneDrive, Box.com and Dropbox, as well as local file storage. More services to come in future.

Cloud storages usually don't offer an hierarchical filesystem but a simple BLOB storage. With help of CloudBlackbox and Solid File System in callback mode you can easily create a scaleable distributed hierarchical file system in the cloud.

CloudBlackbox includes HTTPBlackbox client for secure data transfer over HTTP/HTTPS and basic functionality of PKIBlackbox package for certificate and key management.
