Digital Signatures Explained - Authentication, Integrity & Non-Repudiation

Digital signatures are the trust foundation of PKI — they're how certificates prove identity, code proves it hasn't been tampered with, and emails prove who sent them. This video breaks down exactly how digital signatures work, step by step. 🔑 Key Points: Digital signatures use asymmetric cryptography: sign with private key, verify with public key Three guarantees: authentication, integrity, and non-repudiation Hash-then-sign: the signature covers a hash of the data, not the data itself Real-world uses: TLS certificates, code signing, S/MIME, document signing Digital signatures ≠ electronic signatures — the cryptographic difference matters 📚 Full written guide: https://fixmycert.com/guides/digital-... 🧪 Interactive demo: https://fixmycert.com/demos/digital-s... 🎬 Related Videos: How TLS Works - Handshake, Key Exchange & Encryption Explained:    • How TLS Works - Handshake, Key Exchange & ...   Certificate Anatomy - Every X.509 Field Explained:    • Certificate Anatomy - Every X.509 Field Ex...   S/MIME Email Security:    • S/MIME Email Security — How Certificate-Ba...   🔗 More PKI education: https://fixmycert.com #SSL #TLS #Certificates #PKI #CyberSecurity #DigitalSignatures #Cryptography #NonRepudiation #CodeSigning #DevOps #SRE
