Encryption in LXR is based on the standard AES and is implemented in the strongest form with 256 bits. On top of that, data are processed with CTR, eventually in parallel.
// Low Risk: these algorithms are known since a couple of years and are heavily tested. We do not expect someone to find a bug therein in the future. This is a very important assurance when storing encrypted data for a long time period.
While data is processed in computer memory or saved on the harddisk as files, this is acomplished in a distributed pattern (i.e. non-local). An intended effect where an attacker cannot read the original data, but sees garbage of bytes. This has mild implications on the performance of the system, but drastically increases its security.
