Maybe I'm stupid, but the first example give me private key:
115792089237316195423570985008687907851824985096824206522838950949005526276248
in second example i have your right key:
1012579182250697859766212192512635217927

k1= 5853058856940450056452093598338931896

result = 115792089237316195423570985008687907851824985096824206522838950949005526276248

which n- result = 1012579182250697859766212192512635218089

and:

r1=91569536891656778098714370566123400538808691962301036137348069575478543413371

result: 1012579182250697859766212192512635217927

and this is problem -> any explanation?
