describe what components of cryptography impacted you the most. Cryptography is a science of secure communication between hosts. It includes securing the message which can be only be read by person with the right code. The process is called encryption. And the process in which secure message is decoded is called decryption. There are different types of cryptography - depending on the type of methods being used in the communication. Three popular types of cryptography techniques are - public key, private key and symmetric key cryptography. In each case of public key cryptography, the content is secured with PGP key and you need the same key to read the message. The public key content doesn't have to secret and can be shared with others. Such cryptography is only used for the content that requires security from some sources that doesn't allow open communication. In case of private key cryptography the content is secured and the key is only shared in between two or more private parties.
