Nowadays the Internet provides communications between millions of people, all in all essentially strangers, and all day its use as a slam for the increasingly popular ecommerce. With all this info sub which includes surreptitious communications, commercial transactions, etc., certification becomes a major sham in protecting personal tuition. A mainstay verbalism for sterilise communications is played by Cryptography. Cryptography is the knowledge of securing information while Cryptanalysis is the science of analyzing and breaking substantial communication. They are both part of Cryptology. This paper presents an overview of Cryptography. Cryptography is the field of mathematical techniques related to aspects of information security such as confidentiality, data integrity, entity authentication, and data origin authentication. It enables you to store sensitive information or transmit it across insecure networks (like the Internet) so that still the mean recipien t can read it. A cryptographical algorithmic program (or cipher) is a mathematical function used in the encryption and decryption process. It works in combine with a key (a word, number, or phrase) to encrypt the plaintext. The same plaintext encrypts to distinct ciphertext with different keys. The security of encrypted data is entirely dependent on two things: the forte of the cryptographic algorithm and the secrecy of the key. A cryptosystem is comprised of a cryptographic algorithm, plus all possible keys and all the protocols that make it work.
