ARALOC uses 256 bit AES encryption using a symmetric key system. In a symmetric key system, there is no public key, but rather a single private key that is only released to authenticated users. Each piece of content is encrypted with a unique key. With a 256-bit key, the possibility of an unauthorized user guessing the correct key is 1 in 1077. Scientists predict that it will be nearly 200 years before we are capable of building a computer that has the power to attempt to break this type of encryption.
