签名/验签(ArkTS)

当前指导共提供四种示例，供开发者参考完成签名、验签开发：

具体的场景介绍及支持的算法规格，请参考签名/验签支持的算法。

开发步骤

生成密钥

  1. 指定密钥别名。

  2. 初始化密钥属性集。

  3. 调用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。

签名

  1. 获取密钥别名。

  2. 指定待签名的明文数据。

  3. 获取属性参数HuksOptions，包括两个字段properties和inData。inData传入明文数据，properties传入算法参数配置。

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

  5. 调用finishSession结束密钥会话，获取签名signature。

验签

  1. 获取密钥别名。

  2. 获取待验证的签名signature。

  3. 获取属性参数HuksOptions，包括两个字段properties和inData。inData传入签名signature，properties传入算法参数配置。

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

  5. 调用updateSession更新密钥会话。

  6. 调用finishSession结束密钥会话，验证签名。

删除密钥

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