Sign transaction

[MixMAx123]

Hello,

I need help signing transactions. I have already created an unsigned transaction.

Unfortunately my programmed signing fails. Is there any help here in the forum as I create the Sig r and Sig s? Or a detailed instructions for programmers? Or would like to help me a programmer?

I programmed a Bitcoin Wallet in Java. But the signing does not work yet.

Many Thanks

If I were you, I'd ask that question on stackoverflow, not here. Also, why don't you look into source files of bitcoin or unit tests and see how it's done?

I've got it for myself now. Thanks for your help.
