What type of document does a digital signature relate to?

A digital signature is a cryptographic value attached to an electronic document that confirms the signer's identity and the integrity of the content. Digital signatures are specifically designed for any electronic document, which includes a wide range of formats such as emails, contracts, and even small scripts or macros. This technology ensures that the document has not been altered after signing, providing authenticity and non-repudiation.

This capability makes digital signatures highly versatile and applicable to all kinds of electronic documents, rather than limiting them to physical forms of documents or specific types like financial records or heavily edited materials. The flexibility in application highlights the extensive reach and utility of digital signatures within various electronic communication and documentation practices.
