明文導(dǎo)入密鑰(C/C++)

開(kāi)發(fā)步驟
-
指定密鑰別名keyAlias。 密鑰別名的最大長(zhǎng)度為64字節(jié)。
-
封裝密鑰屬性集和密鑰材料。通過(guò)[OH_Huks_InitParamSet]、[OH_Huks_AddParams]、[OH_Huks_BuildParamSet]構(gòu)造密鑰屬性集paramSet。
- 密鑰屬性集中必須包含[OH_Huks_KeyAlg]、[OH_Huks_KeySize]、[OH_Huks_KeyPurpose]屬性。
- 密鑰材料須符合[HUKS密鑰材料格式]。
- 開(kāi)發(fā)前請(qǐng)熟悉鴻蒙開(kāi)發(fā)指導(dǎo)文檔：
gitee.com/li-shizhen-skin/harmony-os/blob/master/README.md點(diǎn)擊或者復(fù)制轉(zhuǎn)到。
-
調(diào)用[OH_Huks_ImportKeyItem]，傳入密鑰別名和密鑰屬性集，導(dǎo)入密鑰。
