About:
Libuecc is a compact C library designed for elliptic curve cryptography, specifically optimized for the Curve25519 curve. It provides fundamental operations for key exchange and digital signatures with a minimal footprint. Its primary value is enabling efficient public-key cryptography in resource-constrained environments like embedded systems.
Key Features:
  • Extremely small code footprint
  • Optimized for Curve25519
  • Constant-time operations for security
  • C99 compliant and portable
Use Cases:
  • Securing communication in embedded devices
  • Implementing key exchange in fastd VPN
  • Lightweight cryptographic applications
Alternatives:
  • libsodium – More feature-rich but significantly larger; Libuecc is focused on minimalism for specific curves.
  • OpenSSL (ECC) – A comprehensive but heavyweight library; Libuecc offers a much smaller footprint for focused ECC tasks.
