Crypto Keys Java Library

This project wraps public and private keys for common cryptographic functionalities for the following elliptic curves:

Dependencies

  • Java 8
  • Maven

Build instructions

./mvnw package 

Maven repository

Using gradle

// for using ed25519 key pair implementation com.syntifi.crypto:crypto-key-ed25519:VERSION // for using secp256k1 key pair implementation com.syntifi.crypto:crypto-key-secp256k1:VERSION

Using maven

<dependencies> ... <!-- for using ed25519 key pair --> <dependency> <groupId>com.syntifi.crypto</groupId> <artifactId>crypto-key-ed25519</artifactId> <version>VERSION</version> </dependency> <!-- for using secp256k1 key pair --> <dependency> <groupId>com.syntifi.crypto</groupId> <artifactId>crypto-key-secp256k1</artifactId> <version>VERSION</version> </dependency> </dependencies>

How to

Ed25519PublicKey publicKey = new Ed25519PublicKey(); publicKey.readPublicKey("public_key.pem");
Secp256k1PublicKey pubKey = new Secp256k1PublicKey(); publicKey.readPublicKey("public_key.pem");
publicKey.writePublicKey("public_key.pem");
Ed25519PrivateKey privateKey = new Ed25519PrivateKey(); privateKey.readPrivateKey("private_key.pem");
Secp256k1PrivateKey privateKey = new Secp256k1PrivateKey(); privateKey.readPrivateKey("private_key.pem");
privateKey.writPrivateKey("private_key.pem");
byte[] signature = privateKey.sign("Message".getBytes());
 Boolean verified = publicKey.verify(message.getBytes(), Hex.decode(hexSignature));
