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。
