Digital Signatures — CompTIA Security+ (SY0-701) Practice Questions
Digital signatures are a cryptographic mechanism that uses asymmetric key pairs to verify the authenticity and integrity of a message or document, providing both authentication and non-repudiation. On SY0-701, candidates must understand that a sender signs data using their private key, and any recipient can verify the signature using the corresponding public key obtained from a trusted certificate. The exam tests the full digital signature workflow, including its relationship to hashing algorithms, public key infrastructure (PKI), and certificate authorities. Digital signatures are distinguished from digital certificates and encryption, so candidates must be precise about what each mechanism provides and how they interact.
