ملخص الدرس
This lesson delivers a comprehensive study of modern cryptography. It analyzes the mathematical distinction between symmetric (AES) and asymmetric (RSA/ECC) encryption, detailing the hybrid model used in TLS. It covers cryptographic hash functions (SHA-256) and their core mathematical properties, explains the structure and verification of Digital Signatures for non-repudiation, and details Public Key Infrastructure (PKI), Certificate Authorities, and HTTPS.
هتتعلم إيه فى الدرس ده
- Encryption converts plaintext to ciphertext; decryption reverses the transformation.
- Symmetric encryption uses a single shared key (fast, key distribution challenge, e.g., AES).
- Asymmetric encryption uses public and private key pairs (e.g., RSA, ECC).
- Hash functions are one-way mathematical transformations producing fixed-size digests (e.g., SHA-256).
- Digital signatures use the sender's private key to guarantee authentication, integrity, and non-repudiation.
- PKI and Certificate Authorities (CAs) bind public keys to verified domain identities.
- HTTPS combines asymmetric key exchange with symmetric session encryption via TLS.
