鸿蒙开发：Universal Keystore Kit（密钥管理服务）【明文导入密钥(ArkTS)】

明文导入密钥(ArkTS)

分别以导入AES256与RSA2048密钥为例，具体的场景介绍及支持的算法规格

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。
- 密钥属性集同样与密钥生成中指定的密钥属性一致，须包含[HuksKeyAlg]、[HuksKeySize]、[HuksKeyPurpose]属性。
- 密钥材料须符合[HUKS密钥材料格式]，并以Uint8Array形式赋值给[HuksOptions]的inData字段。
调用[huks.importKeyItem]，传入密钥别名和密钥属性集，即可导入密钥。

调测验证

调用[huks.isKeyItemExist]验证密钥是否存在，如密钥存在即表示密钥导入成功。
