Cryptography: hands-on training

Mathematical foundations of modern cybersecurity: symmetric vs asymmetric ciphers (AES, RSA, ECC), secure hashing algorithms, digital signatures, PKI, and TLS 1.3.

What you'll practise: Encrypt, decrypt and sign files with OpenSSL; Compute and compare SHA-2, SHA-3 and HMAC values; Decode layered data with CyberChef; Create a practice certificate authority and issue a certificate; Inspect a real TLS 1.3 handshake.
