//Converts a private key string to PrivateKey
PrivateKey privateKey = PrivateKey.fromStringED25519("302e020100300506032b657004220420d763df96caaabf192c67326e87c32a1ae4571f739022c77d2acaae5dd09cfb13");

//The public key associated with the private key
PublicKey publicKey = PublicKey.fromStringED25519("302a300506032b65700321008f556741dcb5e144e5cabfce5355ad5050ec7a6ea15787a5fd759d616e047d24");
