Secret Contract Development Toolkit - Crypto Tools
⚠️ This package is a sub-package of the secret-toolkit
package. Please see its crate page for more context.
This crate contains common cryptography tools used in the development of Secret Contracts running on the Secret Network.
Note: It has a deep dependency tree and increases compilation times significantly.
Add the following to your cargo.toml
file:
[dependencies]
secret-toolkit = { version = "0.10.0", features = ["crypto"] }
secret-toolkit-crypto = { version = "0.10.0", features = ["hash", "rand", "ecc-secp256k1"] }
Example usage
let deps = mock_dependencies();
let entropy: String = "secret".to_owned();
let prng_seed: Vec<u8> = sha_256(base64::encode(&entropy.clone()).as_bytes()).to_vec();
let mut rng = ContractPrng::new(&prng_seed, entropy.as_bytes());
let private_key: PrivateKey = PrivateKey::parse(&rng.rand_bytes())?;
let public_key: PublicKey = private_key.pubkey();
let message: &[u8] = b"message";
let signature: Signature = private_key.sign(message, deps.api);
Cargo Features
["hash"]
- Provides an easy-to-usesha256
function. Uses sha2.["rand"]
- Used to generate pseudo-random numbers. Uses rand_chacha and rand_core.["ecc-secp256k1"]
- Contains types and methods for working with secp256k1 keys and signatures, as well as standard constants for key sizes. Uses secp256k1.
