This project is to spread info about basic encryption techniques and it's working process in them. Some of the basic encryption methods, which actually date to 17th Century(*not confirmed) are Caesar cipher, Vigenere cipher.
Note:If you want to learn more about cipher techniques, you can really learn them in websites like Brilliant.org , wikipedia.com etc.
There is also an app called 'Crypto' which is available in Play store(for App store,IDK :) ). It provides all tools about ciphers and more advanced techniques like Certificate generation etc.
Link for Crypto is given below:
Note:Crypto doesn't provide info about all cipher techniques, it just provides tools..
