The Internet is one of the most important inventions in human history. It has changed our lives for the better, and it’s now an integral part of our society. We can’t go back to a world without it.

An encryption method that uses the same private (secret) key at both ends of the transmission. Contrast with asymmetric cryptography, which uses a public and private key. See secret key cryptography.

From Caesar ciphers to AES and RSA, Practical Microcontroller Cryptography shows how cryptography actually runs on ...

Many discussions of “hybrid encryption” begin with some debate about just what this means. Hybrid encryption in general refers to the combined use of public-key (asymmetric) cryptography with ...

No one knows when, but crypto-menacing quantum machines are coming. Here's how researchers use quantum mechanics to crack large integers in asymmetric cryptography. Quantum computing continues to ...
