What are the basics of digital signatures? - Tax Craft Hub

A digital signature is a cryptographic method used to ensure the authenticity, integrity, and non-repudiation of digital communications or documents. It involves a pair of keys: a private key, which is used by the signer to create the signature, and a public key, which is used by the recipient to verify it. The signature is unique to both the message and the signer, and if the message is altered in any way after signing, the signature becomes invalid. This ensures that the message hasn't been tampered with and that the sender cannot deny having sent it (non-repudiation). Digital signatures are widely used in legal documents, software distribution, and financial transactions.
