Understanding Digital Signatures

How does a digital signature work?

• A digital signature is created by encrypting a hash of the message with the sender's private key, allowing verification with the sender's public key.

• A digital signature is generated by hashing the entire message without any encryption.

• A digital signature is a physical signature scanned and sent electronically.

• A digital signature is created by simply writing the sender's name on the document.

What are the main components of a digital signature?

• Encryption algorithm, public key, digital certificate

• Public key, digital certificate, encryption key

• Hash function, private key, digital signature, public key.

• Digital certificate, private key, hash algorithm

What is the difference between a digital signature and an electronic signature?

• A digital signature is a type of electronic signature that is always handwritten.

• Digital signatures can only be used for physical documents, whereas electronic signatures are for digital files.

• A digital signature is a secure, cryptographic method of signing documents, while an electronic signature is a general term for any electronic indication of agreement.

• An electronic signature is a legally binding contract, while a digital signature is not.

What algorithms are commonly used in digital signatures?

• SHA-256

• Blowfish

• RSA, DSA, ECDSA

• AES

Can digital signatures be forged? Why or why not?

• No, digital signatures cannot be forged without access to the private key.

• Anyone can create a digital signature without restrictions.

• Digital signatures can be forged with the right software tools.

• Yes, digital signatures can be easily replicated.
