File Encryption and Decryption using Python

Encryption has became a necessity in all forms of communication. Hackers, 3rd party want to steal information from our communication to gather important information about us. To mitigate it we need to ensure whatever we are sending through different channel of communication should remain encrypted. Only the recipient should be able to understand our communication and no one else.

In this video I am going to encrypt a text file using encryption algorithm. The encrypted text file will contain unicode characters that are unreadable.

Once I have generated encrypted text file I will use a decrypt algorithm to decrypt unicode characters into ascii character.

Once we have decrypted the cipher text inside the encrypted file we will compare it with our original file.

I want to thank all the creators of hollywood movie "The Imitation Game". In this movie Alan Turing had played a key role in decrypting enigma code and saved millions of people from world war 2.
