About:
Libtomcrypt is a robust, open-source cryptographic library written in C that provides a wide array of algorithms including symmetric ciphers, public-key cryptography, and hash functions. Its modular design allows developers to include only the components they need, optimizing for size and performance in constrained environments. This makes it an excellent choice for embedded systems and applications requiring custom cryptographic solutions.
Key Features:
  • Extensive algorithm support (AES, Twofish, RSA, ECC, etc.)
  • Highly modular and portable C code
  • Designed for integration into embedded systems
  • Public domain licensing for unrestricted use
Use Cases:
  • Developing secure firmware for IoT and embedded devices
  • Building custom cryptographic protocols and applications
  • Integrating a lightweight crypto library into C-based projects
Alternatives:
  • OpenSSL – Much larger and more complex, but offers more standard protocols and TLS implementation.
  • libsodium – Focuses on modern, high-level APIs and opinionated cryptography, whereas Libtomcrypt is more granular and low-level.
