Crypto Engineering Co. was a British automobile manufacturer based in London, active during the early 20th century. The company operated between 1904 and 1905, during a period marked by the burgeoning automotive industry in the United Kingdom.

Crypto specialized in assembling a limited number of vehicles that utilized a 2-cylinder Tony 1 luber engine, which was mounted on a Dupressoir chassis. The combination of these components reflected the engineering practices of the time, focusing on simplicity and functionality in vehicle design.

Despite its brief existence, Crypto Engineering Co. contributed to the early development of the automotive sector in Britain, showcasing the innovative spirit of the era. However, the company did not achieve long-term success and eventually ceased operations after just a few years.
