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
