help in my code

[FabioCarpi]

I'm redoing the entire bitcoin in php only to understand it better.
buy im facing a bug that i believe is in the 3rd part code...
the 3rd part code is not generating the correct sign, comparing the asm section...

My code: https://github.com/FabioCarpi/MyCoin
ECDSA library: https://github.com/mdanter/phpecc
how to sign: http://bitcoin.stackexchange.com/questions/32628/redeeming-a-raw-transaction-step-by-step-example-required

You would have to point to the code. I can't look at all of your code.

Also, this is just my advice, but please use english naming of your files + comments. It's difficult to navigate.

Sorry about that. The program is in Portuguese. I'm asking for help here because I'm can't find help in my language...

Your code is using the wrong pubkey.

Your pubkey (from bitcoin-qt)
0355bb21eeff72c061adf57064b239d67d5ff77f8c2a1f7b8a2bd4b854dbdab634

Your pubkey (from your code)

[FabioCarpi]

thank you. had not seen it...
i fixed that...
buy i alread got the wrong asm...

there something that i can't understand...
im using this code (https://github.com/Bit-Wasp/bitcoin-lib-php/blob/master/src/RawTransaction.php) to sign...
but why i have to use a random number (line 1122) to sign?
there i will got differents asm...
