The bug I found is about function sm2_sig_gen in crypto/sm2/sm2_sign.c:185 . Explicit formulas: x1,_ = kG , r = (x1 + e) mod N, s = (d + 1)^-1 * (k - rd mod N) mod N We only check r == 0 or r+k == n , but there

RSA sign procession is different from encryption and decryption, that is contains other asymmetric algorithm, Message Digest and Secure Hash Algorithm. And anther difference is that finishing the signature need the private key. It's the opposite of the RSA encryption/decryption process. ...
