Digital Signature in Hindi

This Tutorial Explain What is Digital Signature in Hindi.
A Digital Signature in Hindi (not to be confused with a digital certificate) is a mathematical technique used to validate the authenticity and integrity of a message, software or digital document.
It Covers Points like digital signature in cryptography in hindi, digital signature in network security and digital signature in dbms(advance database management system)
Digital Signature Use Asymatric Key to Encrypt Data.
Digital signatures are often used to implement electronic signatures, a broader term that refers to any electronic data that carries the intent of a signature

How digital signatures work

Digital signatures are based on public key cryptography, also known as asymmetric cryptography. Using a public key algorithm such as RSA, one can generate two keys that are mathematically linked: one private and one public. To create a digital signature, signing software (such as an email program) creates a one-way hash of the electronic data to be signed. The private key is then used to encrypt the hash. The encrypted hash -- along with other information, such as the hashing algorithm -- is the digital signature. The reason for encrypting the hash instead of the entire message or document is that a hash function can convert an arbitrary input into a fixed length value, which is usually much shorter. This saves time since hashing is much faster than signing.
