ZKryptium

GitHub

ZKryptium is a cryptographic library written in Rust which provides an implementation in accordance with:

• BBS+ Signature Scheme
• Blind BBS Signatures
• CL2003 Signature Scheme

This library enables the creation of zero-knowledge proofs, exposing cryptographic primitives facilitating the development of a Verifiable Credentials (VCs) system capable of handling both Anonymous Credentials and Selective Disclosure Credentials.

Adopted by

We’re proud to be adopted by companies around the world. Here are a few of the organizations leveraging our library:

• IOTA Foundation
• SpruceID
• Hushmesh Inc.

Future work

In the future we expect to extend this library to support a new set of post-quantum secure algorithms such as BLNS and zk-STARK.
