Usage

SECP256k1 wrapper for React Native provides the following functionality:

Generating a Random Private Key

To generate a random private key, use the following code:

// Import the wrapper
import SECP256k1Wrapper from 'secp256k1wrapperforrn';

// Generate a random private key
const privateKey = SECP256k1Wrapper.generatePrivateKey();

// Use the private key in your application
console.log(privateKey);

Deriving the Public Key from a Private Key

To derive the public key from a private key, use the following code:

// Import the wrapper
import SECP256k1Wrapper from 'secp256k1wrapperforrn';

// Get the private key
const privateKey = '...'; // Replace with your actual private key

// Derive the public key
const publicKey = SECP256k1Wrapper.derivePublicKey(privateKey);

// Use the public key in your application
console.log(publicKey);

Signing a Message with a Private Key

To sign a message with a private key, use the following code:

// Import the wrapper
import SECP256k1Wrapper from 'secp256k1wrapperforrn';

// Get the private key
const privateKey = '...'; // Replace with your actual private key

// Sign a message
const message = '...'; // Replace with your message
const signature = SECP256k1Wrapper.signMessage(privateKey, message);

// Use the signature in your application
console.log(signature);

Verifying a Signature with a Public Key

To verify a signature with a public key, use the following code:

// Import the wrapper
import SECP256k1Wrapper from 'secp256k1wrapperforrn';

// Get the public key
const publicKey = '...'; // Replace with your actual public key

// Verify a signature
const message = '...'; // Replace with the original message
const signature = '...'; // Replace with the signature
const isValid = SECP256k1Wrapper.verifySignature(publicKey, message, signature);

// Use the validity result in your application
console.log(isValid);

Conclusion

Congratulations! You have successfully learned how to use the SECP256k1 wrapper for React Native. You can now work with random private keys, derive public keys, sign messages, and verify signatures in your React Native applications.
