introduction

Secure Cloud Storage (or SECS) is an application that secures your data before its transferred to a cloud storage provider (such us Amazon S3 service).

SECS encrypts your data using the Asymmetric Encryption Standard (AES), supporting 128, 192 and 256 bits encryption of data.

How does it work?

SECS works as a proxy sitting between your application and the cloud storage service. This enables all and any application to have its data secured without any modifications (or awareness) to the applications normally used. The following picture depicts the common architectural deployment.

How safe is my data?

We have thought long and hard on what encryption algorithms and symmetry type to select and leaned towards AES due to its wide acceptance in the encryption industry and its long standing record of safeness. AES is used throughout a large and homogeneous set of scenarios, from government and military agencies to small and large companies.

But that's not the end of it, selecting an encryption algorithm is just the beginning, implementation is as important (if not more so) than the algorithm itself, we have used one of the most popular implementations out there, making sure usage of the implementation is done right (for the technically savvy crowd, random initialization vectors are used throughout the implementation and custom tailored for each chunk).

So, to keep it simple, the answer is, your data is very safe.
