Electronic signatures, or e-signatures, refer broadly to any electronic process that indicates acceptance of an agreement or a record. The term digital signature is frequently used to refer to one specific type of electronic signature. 1  Typical e-signature solutions use common electronic authentication methods to verify signer identity, such as email, corporate IDs, or a phone PIN. 2  Digital signatures use a specific type of electronic signature.
This is where digital signatures can come in handy. Using a digital signature alone (without encryption) only involves steps 1, 2, 3, 6, and 7. There are two types of digital signature that gpg can apply. A normal signature, where the raw binary data of the signature is included with the original data. And a clear sign signature where the signature is added as readable text (a base64 ascii-armor signature).
