DIGITAL SIGNATURE�
Digital signature is a sort of Cryptography. Cryptography means keeping communications private. It is a practical art of converting messages or data into a different form, such that no one read them without having access to the �key�. The message may be converted using a �code� (in which case each character or group of characters is substituted by an alternative one), or �cipher� (in which case the message as a whole is converted, rather than individual characters). It deals with encryption , decryption and authentication. Download Presentation
