Digital Signature: Exam notes CompTIA Security+

 Digital Signature

Listed below are the items you need to know for the exam:

Digital signatures provide:

• Non-repudiation
• Authentication
• Integrity

Creating the digital signature is a 2 step process:

• First, hash the email/message
• Second, the private key digitally signs (encrypts) the hash

The digital signature is created with the "sender's" keys. 

The digital signature is an encrypted wrapper for the sender's public key.

The recipient's system extracts the public key and decrypts the digital signature to validate the sender.

RSA and DSA (Digital Signature Algorithm) are used to create digital signatures.
