Cryptography before the advent of computers relied on the use of ciphers. A cipher is a mapping from readable text to gibberish, and back again. For instance, a simple cipher would be to add four ...

Encryption is hard. When NSA leaker Edward Snowden wanted to communicate with journalist Glenn Greenwald via encrypted email, Greenwald couldn’t figure out the venerable crypto program PGP even ...

The most simple version of encryption is a basic replacement cipher. If you use numbers to indicate letters in the Latin alphabet, A=1, B=2, et cetera, you can send a message as that code.

The foundations for public key cryptography were first discovered between 1970 and 1974 by British mathematicians working for the U.K. Government Communications Headquarters, the same government ...

Some ciphers have simple keys, others, complex ones. The key for a cipher used by Augustus Caesar, some 2,000 years ago, was simple enough: The receiver just had to shift the alphabet one position.

The solution requires storage of encryption keys — the codes needed to decrypt data — with third-party custodians. Those custodians would not keep these client’s encryption keys.

The idea that the debate is a new one is wholly false. Today’s push and pull is just another iteration of the surveillance and encryption debate we saw in the 1970s, and again in the 1990s.
