PoC : Secure PII workflow with Angular 20, C# BFF, Redis, and Auth0. Opaque tokens + PKCE, AES-256-GCM encryption at rest, PII never stored in browser state.

Lazy AES-GCM in Golang

C++ AES (Advanced Encryption Standard) ECB, CBC, CFB, CTR and GCM modes are implemented.

A Rust and Node.js library that facilitates secure encryption and decryption by converting Ed25519 keys to X25519 keys. It utilizes elliptic-curve Diffie-Hellman (ECDH) to derive a shared secret, which is then used for symmetric encryption with AES-256-GCM.
