CycloneCrypto
Embedded Cryptographic Toolkit

CycloneCrypto Logo

CycloneCrypto is a cryptographic toolkit designed for use in embedded systems. It provides a comprehensive set of cryptographic primitives (hash functions, stream and block ciphers, public key cryptography) that can be used to add security features to your embedded application.
