Cryptography is a very vast topic which contains many techniques to make the data secure. One such Cryptography technique is the public key Cryptography. In the public key Crypto Systems there are two keys, one is the Public key and other is the private key. The public key is made available to the outside world and is in confidential where as the private key is kept secret and is available only to a particular user. Here the public key is kept different from the private key. The public key is used for encryption whereas private key is used for decryption of the message.

As we know that Cryptography is based upon the encryption of the message at the sender side followed by its decryption at receiver side. This encryption and decryption is done by using a key. There are two keys, one at the sender side and one at the receiver side. In the key exchange Cryptography technique some information is exchanged between the source and the destination from time to time and ultimately the sender side key is exchanged with the receiver side key. So, we can say that the key exchange algorithms follow the symmetric key Cryptography approach as the keys used on both sender and the receiver sides are same.

Cryptanalysis is the converse process of Cryptography. Cryptography is science and art of making the message secret, where as Cryptanalysis is the art of cracking the codes and breaking the security. The person who performs the Cryptanalysis is known as the Cryptanalyst. The Cryptanalyst’s job is to decode the secrets either by hook or crook, he keeps on trying different combinations. The performance of a Cryptanalyst depends upon the time he/she takes to decode the data. It means that the lesser the time a Cryptanalyst takes; the better is his/her performance.

Cryptography is the art of secret writing. Cryptography is basically a technique which is used to enforce security standards on the data which we want to send through any network. When the data is going from source to destination then there may arise a case where some body can misuse the data, that data may also contain some important information which is not meant for anybody other than the receiver, so in these cases security becomes a must. At the sender side, the data is encrypted by using a key, and on the receiver side the encrypted data is again decrypted using another key to get back the original data. Note that the keys are kept secret. This concept of encrypting the data at the sender side and decrypting it at the receiver is Cryptography, which can provide security to the data.

Security is a very broad subject that encompasses many aspects. The kind of security every internet user is looking forward to is the network security feature. The most important aspect of network security is cryptography. The word cryptography in Greek means “secret writing”. It refers to the science and art of transforming messages to make them secure and immune to attacks. The science that’s deals with cryptography is really complex as a cryptographic expert must have a decent knowledge of subjects like mathematics, electronics and last but not the least he or she must have a programming background.
