What is the difference between a Digital Signature and an Electronic Signature?

An electronic signature may be any digital mark (like a scanned image), whereas a digital signature uses cryptographic methods (PKI) to provide higher security and non-repudiation. :contentReference[oaicite:7]{index=7}

What is the difference between Signature and Encryption?
