//Converts an ECDSA private key string to PrivateKey
PrivateKey privateKey = PrivateKey.fromStringECDSA("3030020100300706052b8104000a042204208776c6b831a1b61ac10dac0304a2843de4716f98b09147a169f41d7b4d48ad5");

//The public key associated with the private key
PublicKey publicKey = PublicKey.fromStringECDSA("3036301006072a8648ce3d020106052b8104000a032200029bba954cd41e8ab9f05a0b3b038b1c2c35b9bc16b4e38bc67a2e5ebab2fe72fb");
