A digital signature is a type of electronic signature that uses a digital certificate and encryption to verify the authenticity and integrity of a document. Digital signatures are typically used to sign electronic documents, such as PDFs, Word files, or Excel spreadsheets, and are considered to be a secure and legally binding way to sign documents electronically.
Digital signatures use public key cryptography, which involves the use of a private key and a public key to encrypt and decrypt data. When a user creates a digital signature, the private key is used to create a unique digital signature, which is then embedded in the document. When the document is signed, the public key is used to verify the authenticity and integrity of the signature.
Overall, a digital signature is a secure and convenient way to sign electronic documents, and is widely used in industries such as finance, healthcare, and legal. Digital signatures provide a high level of security and assurance, and are considered to be a legally binding and enforceable way to sign documents electronically.
