Convert String to Int using sscanf (C)

[amateur]

Hello.

During coding a keygen i have this issue. The keygenme calculates a SHA-256 which is stored in a string. After that it adds DWORD values of the SHA. Because my english is not so good to explain i put a simpler (similar) example to see whats going on. I have make some progress but i have stuck one this: Why sscanf doesnt put in eax the correct value starting from sha_256[0]. (Eax should contain the value 0x64ec88ca)

How i can fix this?

-Thank you

    sscanf(sha_256, "%8X", &eax);

"%8X"
