The WWII Pigeon Cipher describes a coded message found on the remains of a carrier pigeon discovered in 1982. This message was sent to the curator of the Pigeons at War exhibit at Bletchly Park, however he found it impossible to crack.

In 2012,…

The ADFGVX cipher was developed by Colonel Fritz Nebel and introduced in March 1918. Germany used it as a field cipher during WWI. It was named the ADFGVX cipher for the letters used to create ciphertext, chosen for their distinctiveness in morse…

NESTOR is the NSA-developed speech encryption used by American forces during the Vietnamese War. The encryption was compatible between several devices, including the KY-38 manpack unit, KY-8 vehicular unit, and KY-28 aircraft unit.

The T-52 G-Schreiber was developed around 1930 by Siemens & Halske. It was used by the Germans in WWII in conjunction with the Enigma and Lorenz. Intercepting messages that were in-depth enough to decipher was difficult for Allied codebreakers…

The TypeX was an electromechanical cipher machine used by the British during WWII. It was devloped by Wing Commander O.G.W. Lywood, with the first production batch delivered to the RAF in 1937. As a British variant of the Enigma, versions of it came…

The Triple Data Encryption Standard was derived (3DES) was derived from DES, when DES began to falter as a secure form of encryption and before AES was developed.

As suggested by the title, it works by running DES three times with three different…

The Data Encryption Standard (DES) is an outdated form of encryption that became vulnerable to brute-force attacks, and was replaced by AES. Developed by IBM in the 1970s, it was used by the U.S. government as their official Federal Information…
