CuaimaCrypt library was born on May 28, 2007. The first decision was what kind of algorithm would be, one of block coding or pseudo-random sequences coding bits; after much research and testing we integrate both models into one, developing "Shift Codec", which allows a non-cyclic code with pseudo-random sequence. These Shift Codecs are grouped in Rake Codec, which can process simultaneously 128 bits and these are grouped in sequence of bits by scramblers with four possible operations. The Shift Codecs are chained with other Shift Codecs, which makes his states dependant of the data entered into the process; additionally a sequence of Shift Codec's hopping states. This coding structure allows to extend the security of the algorithm to the particular needs of everyone just adding more blocks. All the initial parameters of the algorithm, seeds, scramblers between blocks, seeds hopping sequence, Shift Codec chainsare initialized by the key who define the Lorenz attractors' states
