I´d like to construct an ECKey from a hardcoded private key but it´s not working…
If I run the code in this example the key import is working just fine. But since I actually want so send money I need to import my own key…
I tried this private key L48r9sYN2dtsWHWwJ1Xez27W7a3X7RvG6obrmVgU2JLTFQeUCnkh and used this site to generate it. When I try to make the private key an ECKey like this:
ECKey key = ECKey.fromPrivate(Base58.decodeToBigInteger("L48r9sYN2dtsWHWwJ1Xez27W7a3X7RvG6obrmVgU2JLTFQeUCnkh"));
I´m getting the exception
Exception in thread "main" java.lang.IllegalArgumentException: private key exceeds 32 bytes: 304 bits
I tried the solution form this question with this code
String priv = "L48r9sYN2dtsWHWwJ1Xez27W7a3X7RvG6obrmVgU2JLTFQeUCnkh"; ECKey key1 = DumpedPrivateKey.fromBase58(TestNet3Params.get(), priv).getKey();
Which leads me to this exception
Exception in thread "main" org.bitcoinj.core.AddressFormatException$WrongNetwork: Version code of address did not match acceptable versions for network: 128 at org.bitcoinj.core.DumpedPrivateKey.fromBase58(DumpedPrivateKey.java:59) at com.javamaster.TicTacToeApplication.main(TicTacToeApplication.java:42)
I tried another solution form this question
byte() b = priv.getBytes(); System.out.println(priv); ECKey key3 = ECKey.fromPrivate(b, true);
It results in the same exception as from the second try.
What is wrong with the key? Should I use another way to generate the private key?
