-# 命令行工具
-
-注意：
-
-* 命令行工具接口在v3版本正式发布前还会有较大调整
-* SM2, SM3, SM4等算法的命令相对比较底层，是对C语言接口的简单封装，命令行的应用开发者需要组合使用这些指令
-
-命令行工具：
-
-* `sm3` 计算SM3杂凑值，支持带公钥和ID的Z值计算
-* `sm3hmac` 计算SM3-HMAC值
-* `sm2keygen` 生成SM2密钥对，以PKCS #8口令加密的PEM格式存储
-* `sm2sign`,`sm2verify` SM2签名和验证，生成DER二进制编码的SM2签名值
-* `sm2encrypt`,`sm2decrypt` SM2加解密，注意只支持较短的消息加密
-* `reqgen` 生成PKCS #10证书签名请求PEM文件
-* `reqparse` 解析打印REQ文件
-* `reqsign` CA用私钥对REQ文件签名，生成证书
-* `certgen`生成自签名证书
-* `certparse` 解析打印证书
-* `certverify` 验证证书链
-
-TLS功能
-
-* `tlcp_client`
-* `tlcp_server`
-* `tls12_client`
-* `tls12_server`
-* `tls13_client`
-* `tls13_server`
-
-私钥总是默认以口令加密的方式存储
-SM3/HMAC-SM3 以二进制的格式输出
-签名和SM2Ciphertext以DER编码输出
-
-
-应该提供一个口令导出密钥的算法，由口令导出密钥
-
-SM4加密需要外部提供key, iv
-HMAC-SM3可以用命令行的方式拼合
-因此没必要提供一个单独的SM4-CBC-HMAC-SM3
