Public Key Cryptography

Abstract Public Key Cryptography is a software model that presents the process of encoding information, in this case the documents contained in a file. The encoding process begins by determining the master file or document that is ready to be encoded, then by applying the combination method, shifting and implementing the pass phrase to the contents of the document, the encoded document will be formed by Encryption function. The contents of the encoded document are then returned back with the pass phrase implementation method, shifting and combinations to form the master document again by decryption function.
