Symmetric vs asymmetric encryption: what's the difference?
One shared key, or a public and private pair? How the two families of encryption work, what each is good at, and why the internet relies on both at once.

AES-256, explained simply
What AES-256 is, what the 256 means, what happens inside the cipher, and why real-world failures come from key handling rather than the algorithm.
AES-GCM vs AES-CBC: which mode should you use?
GCM authenticates, CBC doesn't. Padding oracles, NIST's nonce rules, measured speeds, and why TLS uses GCM while HLS video still uses CBC.
Block cipher vs stream cipher: differences and examples
AES vs ChaCha20 in practice: how block and stream ciphers process data, why CTR and GCM modes blur the line, which is faster on phones, and the nonce-reuse trap.
Types of encryption: algorithms and where each is used
Symmetric, asymmetric, key exchange and hashes: a map of AES, ChaCha20, RSA, ECC and more, which algorithms to retire, and where each one protects a video lesson.
Is AES-128 still secure? Key size vs key handling
Yes, with caveats that have nothing to do with key length: the brute-force maths, what quantum computing changes, GCM and CBC pitfalls, and AES-128 in HLS video.
