WebCryptography is a technique to convert a plain data in to non-readable form. We can convert the plain data into non-readable from using symmetric key cryptography. Symmetric cryptography uses only one secret key to encrypt and decrypt the data. To do the encryption and decryption in symmetric cryptography we need to share a key between two parties. Webcryptography”. Earlier systems for scrambling messages worked well in military or diplomatic applications, where there was a fixed hierarchy of people who were authorized to know the secret keys. But by the 1970s, with large sections of the economy rapidly becoming computerized, the limitations of classical cryptography were com-ing to the fore.
