everal mathematical concepts remain unchanged for centuries, many were never even considered to be expanded upon. Typical cases, such as the ratios of geometric and arithmetic progressions, for example, which until now humanity uses with a singular, unique and fixed value. The search for new elements, new formulas, expansion of concepts such as accelerations and other magnitudes belonging to the field of kinematics, were motivating factors for the Brazilian researcher who created the Infinite Series with Multiple Ratios (SRMs), with whom the author of this article had the honor to work and help in the creation of these new magnitudes of the exact sciences with countless applications. SRMs remain unknown to humanity to this day, even though more than 23 years have passed since the first presentations and publication in a Brazilian technical magazine. The passion for low-level computing made the author of this article see that SRMs have infinite applicability in machine language, data compression, data lookup and cryptography. This article presents a cryptographic method made with these mathematical elements totally unknown to humanity and with surprising results that will be reported here.
