Description
Cryptography, to most people, is concerned with keeping communications private. Indeed, the protection of sensitive communications has been the emphasis of cryptography throughout much of its history. Encryption is the transformation of data into some unreadable form. Its purpose is to ensure privacy by keeping the information hidden even those who can see the encrypted data. Decryption is the reverse of encryption it is the transformation of encrypted data back into some intelligible form. Authentication is as fundamental a part.We use authentication though out our everyday life. Cryptography provides mechanisms for such procedures. A digital signature binds a document to the possessor of a particular key, while a digital timestamp binds a document to its creation at a particular time. While modern cryptography is growing increasingly diverse, cryptography is fundamentally based on problems that are difficult to solve. Cryptography today might be summed up as the study of techniques and applications that depend on the existence of difficult problems. A cryptanalyst attempts to compromise cryptographic mechanisms, and cryptology (from the Greek êñõðôüò ëüãïò, meaning “hidden word”) is the discipline of cryptography and cryptanalysis combined.
So dear friends join this club and explore this world of cryptography !!!!
