使用OpenSSL进行SM2加解密操作涉及几个关键步骤,包括准备OpenSSL环境、生成SM2密钥对、进行加密和解密操作,以及验证结果。以下是详细步骤: 1. 准备OpenSSL环境 首先,确保你的OpenSSL环境支持SM2算法。OpenSSL 1.1.1及以上版本默认支持SM2算法。你可以通过以下命令检查你的OpenSSL版本: bash openssl version 如果版本低于1.1...

Using the interfaces, it is pretty convenient to implement these algorithms of asymmetric RSA or SM2 encryption decryption signature and verification. This paper sorted out the usage of OPENSSL EVP C-lauguage interface, and implement the SM2 and RSA encrypt decrypt signature and verify. Combining ...
