Warning
It is heavily advised against using this library for new consensus implementations and to use established spec-conformant libraries like supranational/blst as this library codifies primitives predating the final IETF spec and includes a non-standard (now legacy) scheme.
This library has not undergone a formal security review.
dash-pkc¶
This crate supplies the curve primitives for signing, verifying and encrypting used by the Dash Base SDK for consensus-stable types, including
- Distinct byte bag and operative types to allow parsing without pulling in crypto dependencies with native zeroization and constant-time comparison.
- A bug-compatible implementation of the sunset BLS12-381 scheme used by the reference implementation (also known as "legacy" or Chia scheme) and the current active (i.e. "basic") scheme.
- Shared DH secret derivation and encryption using BLS12-381's integrated encryption scheme.
- A consensus-compatible wrapper around secp256k1 with support for DER (en/de)coding, recoverable signatures and Bitcoin-derived compression semantics.
- Scalar and point tweaks for BLS12-381 and secp256k1
Usage¶
To import dash-pkc to your project, add the following to the [dependencies] section in Cargo.toml

Enables secp256k1 operations backed by rust-secp256k1. Byte types are available without enabling this feature. |
|
eddsa |
Enables ed25519 operations backed by ed25519-dalek. Byte types are available without enabling this feature. |
|
full |
Enables all features and std support. |
|
serde |
