明文導入密鑰(ArkTS)

分別以導入AES256與RSA2048密鑰為例，具體的場景介紹及支持的算法規格

開發步驟

指定密鑰別名keyAlias。密鑰別名的最大長度為64字節。
封裝密鑰屬性集和密鑰材料。
- 密鑰屬性集同樣與密鑰生成中指定的密鑰屬性一致，須包含[HuksKeyAlg]、[HuksKeySize]、[HuksKeyPurpose]屬性。
- 密鑰材料須符合[HUKS密鑰材料格式]，并以Uint8Array形式賦值給[HuksOptions]的inData字段。
調用[huks.importKeyItem]，傳入密鑰別名和密鑰屬性集，即可導入密鑰。

調測驗證

調用[huks.isKeyItemExist]驗證密鑰是否存在，如密鑰存在即表示密鑰導入成功。
