CrypTool Software which allows encryption of text using historic algorithms The Enigma Machine In World War II the Germans made use of an electro-mechanical rotor based cipher Known as The Enigma Machine. Allied cipher machines used in WWII included the British TypeX and the American SIGABA. The ADFGVX Cipher invented by Colonel Fritz Nebel in 1918. The key for this algorithm is a six-by-six square of letters, used to encode a 36-letter alphabet. The Playfair Cipher invented in 1854 by Cha...

These are usually the encryption of a message digest with the senders private key. In order to verify them, the recipient uses the senders public key. They are considered good if they provide the following. Authentication Integrity Non-repudiation Digital Signature It is a digital document that contains a public key and some information to allow your system to verify where they key came from. This is the most common way to distribute pubic keys in asymmetric cryptography. Digital Certif...
