1. 2. 3. 4. 在上面的代码中,我们首先创建一个KeyPairGenerator实例,使用"EC"算法和"BC"提供者。然后,我们使用ECGenParameterSpec指定SM2的p256曲线参数,并使用随机数初始化密钥对生成器。最后,我们调用generateKeyPair()方法生成密钥对。 2. 获取公钥和私钥 生成密钥对后,我们可以通过以下代码来获取公钥和私钥。

crypto_acipher_gen_ecc_key( ) Yes, these functions can be used to generate an SM2 key pair with key_type = TEE_TYPE_SM2_DSA_KEYPAIR. What makes you think TEE_ERROR_SIGNATURE_INVALID is caused by an invalid key pair? You can perhaps check that the key pair generated by crypto_aciphe...
