以明文导入ECC密钥为例。具体的场景介绍及支持的算法规格
在CMake脚本中链接相关动态库 target_link_libraries(entry PUBLIC libhuks_ndk.z.so)开发步骤 指定密钥别名keyAlias。 密钥别名的最大长度为64字节。 封装密钥属性集和密钥材料。通过[OH_Huks_InitParamSet]、[OH_Huks_AddParams]、[OH_Huks_BuildParamSet]构造密钥属性集paramSet。 密钥属性集中必须包含[OH_Huks_KeyAlg]、[OH_Huks_KeySize]、[OH_Huks_KeyPurpose]属性。密钥材料须符合[HUKS密钥材料格式]。开发前请熟悉鸿蒙开发指导文档gitee.com/li-shizhen-skin/harmony-os/blob/master/README.md点击或者复制转到。 调用[OH_Huks_ImportKeyItem]传入密钥别名和密钥属性集导入密钥。 /* 以下以明文导入ECC密钥为例 */
