Getting Started

Requirements

• Rust (>= 1.65)
• Cargo (>= 1.65)
• The ZKryptium CL03 implementation also depends on the Rug crate which depends on GMP, MPFR and MPC libraries through the low-level FFI bindings in the gmp-mpfr-sys crate, which needs some setup to build; the gmp-mpfr-sys documentation has some details on usage under GNU/Linux, macOS and Windows.

Usage

BBS+:

[dependencies]
zkryptium = { version = "0.3.0", default-features = false, features = ["bbsplus"] }

CL2003:

• see the requirements above

[dependencies]
zkryptium = { version = "0.3.0", default-features = false, features = ["cl03"] }

Examples

Take a look at the examples.

You can run the example based on the BBS+ Signature Scheme with:

cargo run --example bbsplus <ciphersuite>

Available Ciphersuites:

• BLS12-381-SHA-256
• BLS12-381-SHAKE-256

You can run the example based on the CL2003 Signature Scheme with:

cargo run --example cl03 <ciphersuite>

Available Ciphersuites:

• CL1024-SHA-256

Test

To test the library you can launch the test vectors with:

cargo test
