How digital signature work

What is the digital signature

A digital signature is a cryptographic method used to validate the authenticity and integrity of a digital message or document. It serves as a virtual equivalent of a handwritten signature or a stamped seal, ensuring that the signer is who they claim to be and that the document has not been altered after signing. Digital signatures are based on public key infrastructure (PKI), which involves a pair of keys: a private key, known only to the signer, and a public key, which can be shared with others to verify the signature.

Legal use of the digital signature

In the United States, digital signatures are legally recognized under the Electronic Signatures in Global and National Commerce (ESIGN) Act and the Uniform Electronic Transactions Act (UETA). These laws establish that electronic signatures hold the same legal weight as traditional handwritten signatures, provided that both parties consent to use electronic means for signing. This legal framework supports the validity of digital signatures in various transactions, including contracts, agreements, and official documents.
