Although the Enigma was cracked, and WW2 was over, cryptography was still changed forever. What used to be done with pen and paper is now being done with devices. Codes that were once cracked by linguists are now cracked by mathematicians. It was the beginning of a new era. And coinciding with this new era

Today I learned about quantum cryptography, the use of quantum mechanics to perform cryptographic functions. One of the most useful applications of quantum mechanics in cryptography is quantum key distribution, a method of distributing keys between two parties without a third party intercepting it. The nature of quantum communication means that if a third party

After the Vignere cipher was cracked, cipher technology stagnated for a long period of time. New ciphers were invented, but all these ciphers were easily cracked, and private transmissions, especially in the military, were being cracked left and right. That was until Arthur Scherbius invented a device called the Enigma. The Enigma took advantage of

Right now, cryptography is still a developing science. Different types of ciphers are still being tried and tested, and while many are far too complicated for me to cover in detail, hardly any cipher that we use is completely indecipherable. Except for one. And it’s not even that new. The one-time pad cipher, as it
