A digital signature is an electronic form of a signature that can be used to authenticate the identity of the sender of a message or the signer of a document. It is used to verify that the individual sending or signing the document is who they say they are.
For example, when a user registers for a website, they may be asked to provide a digital signature. This signature is then used to verify the user’s identity and ensure that the information they provided is accurate. The digital signature is also used to ensure that the user has not tampered with the information they provided.
