title: How derive ed25519 (eddsa) public key from private key using Java
body: <p>I am looking into <a href="https://github.com/str4d/ed25519-java" rel="nofollow noreferrer">https://github.com/str4d/ed25519-java</a> library as well as some other libraries like BouncyCastle, but I am so far unsuccessful in generating a public key out from a private key. I am not interested in generating a key pair because I already have a private key and am interested in generating the corresponding public key only.</p>
