SM2的加解密功能是否支持C1C2C3的拼接格式#38

最近在做与第三方硬件设备的通信对接功能，要使用国密算法，第三方提供了他们加密使用的工具是Python的gmssl的国密功能，然后我用gmssl-java调用gmssl的C库函数实现加密功能，发现现在的gmssl-java是不是只支持asn1格式的加解密调用，因为我看了第三方的gmssl的源码，发现他们的加密解密算法是直接返回C1C2C3格式的拼接后的二进制文件，他们不支持asn1的加解密，有什么好的办法么？是因为调用的底层的C库函数不支持么？下面附上第三方提供的源码文件内容

                              最近在做与第三方硬件设备的通信对接功能，要使用国密算法，第三方提供了他们加密使用的工具是Python的gmssl的国密功能，然后我用gmssl-java调用gmssl的C库函数实现加密功能，发现现在的gmssl-java是不是只支持asn1格式的加解密调用，因为我看了第三方的gmssl的源码，发现他们的加密解密算法是直接返回C1C2C3格式的拼接后的二进制文件，他们不支持asn1的加解密，有什么好的办法么？是因为调用的底层的C库函数不支持么？下面附上第三方提供的源码文件内容
