Cryptography Fundamentals — Cybersecurity Mind Map

22. Cryptography Fundamentals

Cryptography is the mathematical foundation of all digital security. This mind map covers symmetric, asymmetric encryption, hashing, and the protocols securing the modern internet.

Topics Covered

  • Symmetric: AES-256, ChaCha20
  • Asymmetric: RSA, Elliptic Curve
  • Diffie-Hellman key exchange
  • Hash functions: SHA-256, SHA-3
  • Digital signatures and non-repudiation
  • PKI and X.509 certificates
  • TLS 1.3 handshake
  • Cryptographic attacks
  • Post-quantum cryptography
