通用密钥库基础概念
在使用通用密钥库完成应用开发前,开发者需要了解以下相关概念,以下概念将贯穿整个开发过程。
可信执行环境(TEE)
可信执行环境(Trusted Execution Environment),简称TEE,是存在于智能手机、平板电脑,或任意移动设备主处理器中的一个安全区域,确保各种敏感数据在一个可信环境中被存储、处理和受到保护。TEE为授权安全软件,也称为“可信应用”提供一个安全的执行环境,通过实施保护、保密性、完整性和数据访问权限确保端到端的安全。
密钥材料格式
针对不同密码算法的密钥对、公钥、私钥,HUKS为其密钥材料定义了一套格式,该格式在密钥导入、导出等场景使用。
密钥对材料格式
密钥对材料 = 密钥对材料Header + 密钥对材料原文
开发前请熟悉鸿蒙开发指导文档:gitee.com/li-shizhen-skin/harmony-os/blob/master/README.md

以RSA密钥为例,应用需要申请一个Uint8Array,按照RSA密钥对材料内存排布格式,将各个变量赋值到对应的位置。
下图为RSA密钥材料内存结构为例,其他算法格式见样例下方表格。
其中,密钥算法的值取自枚举类[HuksKeyAlg]。

公钥材料格式
在公钥导出/导入时,密钥材料采用标准的X.509规范的DER格式封装。
如下是一个DER编码的ECC公钥:
let eccP256PubKey = new Uint8Array([0x30, 0x59, 0x30, 0x13, 0x06, 0x07, 0x2a, 0x86, 0x48, 0xce, 0x3d, 0x02, 0x01, 0x06, 0x08, 0x2a,0x86, 0x48, 0xce, 0x3d, 0x03, 0x01, 0x07, 0x03, 0x42, 0x00, 0x04, 0xc0, 0xfe, 0x1c, 0x67, 0xde,0x86, 0x0e, 0xfb, 0xaf, 0xb5, 0x85, 0x52, 0xb4, 0x0e, 0x1f, 0x6c, 0x6c, 0xaa, 0xc5, 0xd9, 0xd2,0x4d, 0xb0, 0x8a, 0x72, 0x24, 0xa1, 0x99, 0xaf, 0xfc, 0x3e, 0x55, 0x5a, 0xac, 0x99, 0x3d, 0xe8,0x34, 0x72, 0xb9, 0x47, 0x9c, 0xa6, 0xd8, 0xfb, 0x00, 0xa0, 0x1f, 0x9f, 0x7a, 0x41, 0xe5, 0x44,0x3e, 0xb2, 0x76, 0x08, 0xa2, 0xbd, 0xe9, 0x41, 0xd5, 0x2b, 0x9e
]);
私钥材料格式
复用密钥对的材料格式,私钥材料的封装是把密钥对材料Header中的公钥部分的长度字段置0,同时密钥对材料原文部分拼接私钥材料即可。
私钥材料 = 密钥对材料Header + 私钥材料原文
