Espressif is on fire! And the CPU even has SIMD instructions!

RISC-V cores is a big deal for embedded systems because now compiling for SoCs is only a matter of `rustup target add riscv32imac-unknown-none-elf` instead of downloading half-broken proprietary toolchains and SDKs.

Take a look at https://kerkour.com/introduction-to-embedded-development-wit... and https://kerkour.com/rust-esp32-pentest to get started with modern (Rust ;) embedded development.

The attack would be like: attacker has read/write access to the database but not to the code of the backend service. Attacker swaps the hash of a targeted API key with the hash of their own API key. Attacker has now access to the resources of the targeted organization when using their own API key.

While it's true that API keys are basically prefix + base32Encode(ID + secret), you will want a few more things to make secure API keys: at least versioning and hashing metadata to avoid confused deputy attacks.

Here is a detailed write-up on how to implement production API keys: https://kerkour.com/api-keys
