Thanks for the link.

You can download this entire Handbook of Applied Cryptography for free [1].

Recently the authors also provided online course and video namely:

- Cryptography 101: Building Blocks (fundamental cryptographic primitives) [2]

- Cryptography 101: Real-World Deployments (PKI, TLS, Bluetooth, AWS, Signal) [3]

Other courses and video includes:

- The Mathematics of Lattice-Based Cryptography (introductory course)

- Kyber and Dilithium (standardized lattice-based cryptosystems)

- Hash-based signature schemes (LMS, XMSS, SPHINCS+)

- Error-Correcting Codes (linear, Hamming, Golay, cyclic, BCH, Reed-Solomon codes

I don't remember if it links to it, but this pairs well with https://cryptopals.com/, which are practical examples of many of these theories.

this is the type of crypto i like

you don't realize crypto (bitcoin and others) are heavily based on "this" crypto algorithms.

You wouldn't happen to be a cryptobro yourself, would you?
