Cryptography for the Everyday Developer: Number Theory for Public Key Cryptography

This is an article in a series on Cryptography for the Everyday Developer . Follow along to learn the basics of modern cryptography and encryption. Modern cryptography relies heavily on number theory. One of the simplest but most important tools in the number theorist’s toolkit is the Euclidean algorithm. This algorithm, and its extension, the extended Euclidean algorithm, form the basis for…
