Nano-SHA3
Cryptographic Hash Function for Embedded Systems
1,456B SHA-3 | ARM Cortex-M0/M4/M33 | ≤384B stack | constant-time security | NIST-validated
Embedded Cryptography for Resource-Constrained Microcontrollers
While full cryptographic libraries offer dozens of algorithms, they often require 20KB+ flash and aren't optimized for embedded systems like Cortex-M0. Nano-SHA3-256 does one thing exceptionally well: SHA-3-256 in 1,456 bytes.

Embedded Systems Ready
no_std compatible, zero heap allocation, bounded stack usage for bare-metal firmware
Embedded Cryptography Size Optimization
Advanced optimization using nightly Rust with -Z build-std for maximum size reduction in embedded systems. Direct ELF measurement of .text + .data sections:
Ideal Embedded Applications
- IoT sensors and devices with 32-64KB flash budgets requiring cryptographic integrity
- Battery-powered embedded systems where code size directly impacts power consumption
- Safety-critical firmware requiring minimal, auditable cryptographic code
- Secure boot and firmware verification on resource-constrained microcontrollers
- Cost-sensitive products using smaller, cheaper MCUs without sacrificing security
