Hello,

I am sorry, I can't understand Mandarin, but based on Google translate, looks like you are looking for a sample code that explains how to create a keypair using NSS functions. You can check this sample code from MDN - Sample code for PK11_generateKeyPair.

Please check this and let us know if you were successful in generating a keypair.

谢谢

Thank you for the same, but i have alread solved the question.Yesteday I meant that the NSS is enable for ecc with an NSS_ENABLE_ECC flag, but I didn't find an ECC params to fill the PK11_GenerateKeyPair argv. Now i have searched the website and found that file named "\nss\cmd\certutil\keystuff.c" told me how to fix the params for ECC not RSA.

Now my problem is turned to be how to make a SM2 arg. SM2 is a kind of ECC. It is a chinese official standard.
