B<SM2> signatures can be generated by using the 'DigestSign' series of APIs, for instance, EVP_DigestSignInit(), EVP_DigestSignUpdate() and EVP_DigestSignFinal(). Ditto for the verification process by calling the 'DigestVerify' series of APIs. +Note that the SM2 algorithm requires the presence of the public key for signatures, +as such the B<OSSL_PKEY_PARAM_PUB_KEY> option must be set on any key used in signature +generation. Before computing an B<SM2> signature, an B<EVP_PKEY_CTX> needs to be created, and an B<SM2> ID must be set for it, like this: |
