charm
A Python framework for rapidly prototyping advanced cryptosystems like ABE, IBE, threshold ECDSA, and zero-knowledge proofs.
What is charm?
Charm is a Python-based framework for rapidly prototyping and implementing advanced cryptosystems. It provides a comprehensive library of cryptographic schemes, including attribute-based encryption, identity-based encryption, threshold signatures, and zero-knowledge proofs, all designed to reduce development complexity. The framework uses a hybrid architecture where performance-critical operations are in C, while schemes are written in high-level Python for readability and rapid iteration.
Cryptography researchers, security engineers, and developers who need to implement, test, or prototype advanced cryptographic protocols such as ABE, threshold ECDSA, or ZKPs without building everything from scratch.
Developers choose Charm for its extensive, production-ready implementations of cutting-edge cryptosystems, its hybrid design that balances performance and prototyping speed, and its focus on minimizing code complexity to accelerate cryptographic research and development.
