Definition of Digital Signatures
A digital signature is a cryptographic technique used to validate the authenticity and integrity of a message or document. It serves as a virtual fingerprint, unique to the signer, which quickly confirms that the document has not been altered. Digital signatures employ asymmetric cryptography. In this context, two keys are used: a private key, which is kept secret by the signer, and a public key, which can be widely distributed. When a signature is applied to a document using the private key, it becomes verifiable by anyone who possesses the corresponding public key.
How Digital Signatures Work
The operation of digital signatures relies on a straightforward but effective process. The signer first creates a hash of the document—this hash is a condensed version of the data. The hash is then encrypted using the signer's private key, producing the digital signature. When the recipient receives the document, they can decrypt the signature with the signer's public key, revealing the original hash. They then independently compute the hash of the received document and compare it to the hash derived from the signature. If the two hashes match, it confirms that the document is untampered and authentically signed.
