In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.
The Pigpen cipher offers little cryptographic security. It differentiates itself from other simple monoalphabetic substitution ciphers solely by its use of symbols rather than letters, the use of which fails to assist in curbing cryptanalysis.
The Enigma machine was considered so secure that it was used to encipher the most top-secret messages. The Enigma has an electromechanical rotor mechanism that scrambles the 26 letters of the alphabet. In typical use, one person enters text on the Enigma's keyboard and another person writes down which of the 26 lights above the keyboard ...

Based on how various sentences are related to one another in the memory space of the neural network, Google’s language and AI boffins think that it has. A visualization of the translation system...
A code talker was a person employed by the military during wartime to use a little-known language as a means of secret communication. The term is most often used for United States service members during the World Wars who used their knowledge of Native American languages as a basis to transmit coded messages.
Tech giants Google, Microsoft, and Facebook are all applying the lessons of machine learning to translation, but a small company called DeepL has outdone them all and raised the bar for the field.
Cryptanalysis of the Enigma. The Enigma machine was used commercially from the early 1920s and was adopted by the militaries and governments of various countries—most famously, Nazi Germany.
In cryptology, a code is a method used to encrypt a message that operates at the level of meaning; that is, words or phrases are converted into something else. A code might transform "change" into "CVGDK" or "cocktail lounge".
DeepL, which builds automated text translation and writing tools that compete against the likes of Google Translate and Grammarly, said on Wednesday that it has raised an additional $300 million ...
