About


dalek-cryptography is a collection of libraries providing safe, mid-level APIs for cryptographic primitives, aimed at making it faster and easier to implement cryptographic protocols such as key agreement, signatures, anonymous credentials, range proofs, and zero-knowledge proof systems.

Other libraries aim to provide well-designed APIs for protocol users, but do not aim to provide well-designed API for protocol implementers. The result is that implementing new protocols often requires using unsafe internal APIs which were never intended for reuse.

Our goal is to provide both safe, mid-level APIs aimed at implementors of cryptographic protocols, as well as implementations providing safe, high-level APIs aimed at users of cryptographic protocols.

We hope to stabilise these libraries to production-quality versions soon, but—for now—they should be used for research.
