Else, you cannot decrypt the data. Private keys are two types. The sender uses one private key and the receiver uses one other private key. I have given in this post about 8 encryption methods. Flow Diagram of Encryption image courtesy by digit.in   Different Encryption Methods Classic Cipher Random Key Generation RSA Token Hash Functions Mac value - Message Authentication code Key Hash TLS Protocol Authenticated Cipher  1. Classic Cipher. The best example is this kind of algorithm was used in world war -II communication machines. 2. Random Key Generations. One kind of security. They use an algorithm that sends random numbers. People use that number as a password.  3. RSA Token. Every 30 seconds a token is generated. Mostly people use fo...
