A quick definition of digital signature:
A digital signature is like an electronic fingerprint that proves who sent a message or document. It's a special code that makes sure nobody can change the message or pretend to be someone else. It's like when you sign your name on a piece of paper, but it's done on a computer instead.
A more thorough explanation:
A digital signature is an electronic version of a person's signature. It's like a unique electronic fingerprint that identifies the signer. It's a way to verify that a message, email, credit card transaction, or digital document is authentic and hasn't been tampered with.
For example, when you sign a document with a pen, your signature is unique to you and can be used to verify that you signed the document. Similarly, a digital signature is unique to the signer and can be used to verify that the digital document was signed by the correct person and hasn't been altered.
Overall, a digital signature is a secure way to ensure that digital communications are authentic and haven't been tampered with.
