加解密(C/C++)

以AES256、RSA1024、SM2和DES64为例，完成加解密。具体的场景介绍及支持的算法规格，请参考加解密支持的算法。

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

生成密钥

  1. 指定密钥别名，密钥别名命名规范参考密钥生成介绍及算法规格。

  2. 初始化密钥属性集。

  3. 调用OH_Huks_GenerateKeyItem生成密钥，具体请参考密钥生成。

除此之外，开发者也可以参考密钥导入，导入已有的密钥。

加密

  1. 获取密钥别名。

  2. 获取待加密的数据。

  3. 调用OH_Huks_InitParamSet指定算法参数配置。

    文档中提供多个示例，当使用不同算法时，请注意配置对应参数。

    详细规格请参考加密/解密介绍及算法规格。

  4. 调用OH_Huks_InitSession初始化密钥会话，并获取会话的句柄handle。

  5. 调用OH_Huks_FinishSession结束密钥会话，获取加密后的密文。

解密

  1. 获取密钥别名。

  2. 获取待解密的密文。

  3. 调用OH_Huks_InitParamSet指定算法参数配置。

    文档中提供多个示例，当使用不同算法时，请注意配置对应参数。

    • 使用AES算法解密，用例中选取的分组模式为GCM时，必须要填参数NONCE和参数AEAD，AAD可选，请见开发案例：AES/GCM/NoPadding。
    • 其余示例参数与加密要求一致。

    详细规格请参考加密/解密介绍及算法规格。

  4. 调用OH_Huks_InitSession初始化密钥会话，并获取会话的句柄handle。

  5. 调用OH_Huks_FinishSession结束密钥会话，获取解密后的数据。

删除密钥

当密钥废弃不用时，需要调用OH_Huks_DeleteKeyItem删除密钥，具体请参考密钥删除。
