DIGITAL SIGNATURE

A digital signature is an electronic and cryptographic technique that secures the content by providing a virtual shield against security threats on both online communications as well as documents. It ensures the authenticity, integrity, non-repudiation of digital message or document by cryptographically verifying. A quick primer on how digital signatures work, 1) Generation of Key Pair: The process starts by generating a pair of cryptographic keys — the private and public. The private key is know only to the owner, whereas the public one can be spread among all others. 2) Signing:* When a hash (a fixed-size string of characters) is created from the document or message to be signed with the help of hash function. The prepared hash is then encrypted with the sender's private key to produce a digital signature. 3) Signature Verification: To verify signature, the recipient decrypts it with sender's public key and gets back to hash. The receiver then creates a hash of the received document and checks it with decrypted-message-hash. It verifies that the document has not been changed and was signed by someone in possession of a matching private key. 4) Integrity and Trust: A digital signature attests that the document was not altered in any manner since it had been signed, also to verify that who is signing the said document. Digital signatures are very common in smart contracts and numerous other applications, including email, software distribution, financial transactions etc to name a few at all the places where some information needs a secure way of authenticating and ensuring that integrity of digital communication. 🔍 Dive Deep into Digital Forensics! 🔍 Welcome to our comprehensive guide on Digital Forensics, your one-stop destination for gaining essential knowledge and skills in this fascinating field.
