Charm Crypto for Mac OS X is a framework for rapidly prototyping advanced cryptosystems. Based on the Python language, it was designed from the ground up to minimize development time and code complexity while promoting the reuse of components.
Charm uses a hybrid design: performance intensive mathematical operations are implemented in native C modules, while cryptosystems themselves are written in a readable, high-level language.
Charm also provides a number of new components designed to facilitate the fast development of new protocols and schemes.
Charm ships with a library of implemented cryptosystems. This library includes public key encryption schemes, identity-based encryption schemes, attribute-based encryption schemes, digital signatures, privacy-preserving signatures, commitment schemes, zero-knowledge proofs, and interactive protocols such as anonymous credential and oblivious transfer schemes.
Here are some key features of "Charm Crypto":
· Support for various mathematical settings, including integer rings/fields, bilinear and non-bilinear Elliptic Curve groups.
· Base crypto library, including symmetric encryption schemes, hash functions, PRNGs.
· Standard APIs for constructions such as digital signature, encryption, commitments.
· A “protocol engine” to simplify the process of implementing multi-party protocols.
· An integrated compiler for interactive and non-interactive ZK proofs.
· Integrated benchmarking capability
Requirements:
· 2.6 MB of disk space
· Python
