# CosmWasm Crypto

NOTE: This is a fork of the original cosmwasm-storage repository adapted for use in [SecretNetwork](https://scrt.network)'s Secret Contracts.

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 sepc256k1
  scheme, for Cosmos signature / public key formats.
- `ed25519_verify()`: Digital signature verification using the EdDSA ed25519
  scheme, for Tendemint signature / public key formats.
- `ed25519_batch_verify()`: Batch digital signature verification using the EdDSA
  ed25519 scheme, for Tendemint signature / public key formats.

## Benchmarking

```bash
cd packages/crypto
cargo bench
```
