Cryptography for Security People

AES, RSA, ECC, hashes, TLS, post-quantum — without the math degree

Practical cryptography for engineers who need to *use* it correctly. Symmetric (AES, modes, padding), asymmetric (RSA, ECC), hashing (SHA-2/3, BLAKE), MACs and AEAD, TLS internals, certificate validation, post-quantum migration (CRYSTALS-Kyber, Dilithium). Hands-on labs with cryptopals-style attacks.
