Thanks for your PR @a3f. Could you please rebase master branch to check if CI issue in your PR is fixed? |
We already check that the RSA *key is not NULL in jose_openssl_jwk_from_RSA(), but fail to do so for EC_KEY *key in jose_openssl_jwk_from_EC_KEY(). But EVP_PKEY_get0_EC_KEY() can return NULL too, e.g., if the EVP_PKEY comes from an OpenSSL provider that is not creating a keymgmt instance for a public key and the default provider is not loaded[1]. Instead of crashing inside OpenSSL when we pass a NULL pointer to EC_KEY_get0_private_key(), detect this case and return gracefully.
