# CosmWasm Crypto

[![cosmwasm-crypto on crates.io](https://img.shields.io/crates/v/cosmwasm-crypto.svg)](https://crates.io/crates/cosmwasm-crypto)

This crate implements cryptography-related functions, so that they can be
available for both, the [cosmwasm-vm](`https://crates.io/crates/cosmwasm-vm`)
and [cosmwasm-std](`https://crates.io/crates/cosmwasm-std`) crates.

## Implementations

- `secp256k1_verify()`: Digital signature verification using the ECDSA secp256k1
  scheme, for Cosmos signature / public key formats.
- `secp256r1_verify()`: Digital signature verification using the ECDSA secp256r1
  scheme, for Cosmos signature / public key formats.
- `ed25519_verify()`: Digital signature verification using the EdDSA ed25519
  scheme, for Tendermint signature / public key formats.
- `ed25519_batch_verify()`: Batch digital signature verification using the EdDSA
  ed25519 scheme, for Tendermint signature / public key formats.

## Benchmarking
