Blubox uses powerful 256-bit AES encryption technology to protect Blubox archives from unwanted intruders. Simply choose a password when you create a new Blubox archive and it will be virtually impossible for an unauthorized person to access your data.

Even if your laptop or USB key falls into the wrong hands, or your email is intercepted, your Blubox archives can never be opened without your permission.

What is Binary Encryption?
Encryption is almost the opposite of compression. Compression relies upon repeated patterns within the data while encryption tries to remove all patterns from the data. The whole point of encryption is to produce data which conveys no immediate information and defies interpretation. The success of an encryption algorithm depends on that ability to distort data into an unrecognizable and pattern-less series of values.

Encryption algorithms typically operate by applying a mathematical transformation on the data it is encrypting. Additionally, a unique password or encryption key is supplied to the algorithm to be incorporated into the transformation. Given the same password or key, this process can be reversed through decryption to recover the original data. Due to the deterministic nature of mathematical operations, an encryption algorithm usually undergoes years of professional and academic scrutiny before it is accepted as a viable encryption mechanism.

The size of the encryption key used by an algorithm is often used to gauge the strength or protectiveness of that algorithm. The reasoning behind this is that there are more combinations of key values in longer keys than in shorter keys, thus making any single encryption key more difficult to guess using the brute force method (trying every possible key until the correct one is found). It is important to remember that the size of an encryption key is irrelevant if the underlying algorithm itself is faulty.

Blubox uses the TEA algorithm with a 256 bit (32 character) key.
