# What are digital signatures? * A digital signature is a cryptographic method to express agreement and validate the authenticity of a digital document. * Digital signatures allow parties to sign documents digitally, while providing an improved degree of authenticity compared to standard electronic signatures. * When coupled with strong identification standards, digital signatures can be equivalent to legally binding, traditional, wet-ink signatures. * In the UK and the European Union, digital signatures are considered legally binding when signatory identities have been verified by “Trust Service Providers” --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
