HarmonyOS 鸿蒙Next 对称加密

1. 有AES/CBC/NoPadding相关加密算法的demo吗？

2. cryptoFramework.createCipher(‘AES/CBC/NoPadding’)创建会直接报错:

Error: create C cipher fail!

{“code”:801}

代码如下:

private async executeEncrypt(content: Uint8Array, encryptKey: Uint8Array, iv: Uint8Array): Promise<Uint8Array> {
try {
//1.创建密钥生成器
let generator = cryptoFramework.createSymKeyGenerator(‘AES128’)
//2.使用密钥生成器将密钥转换成 cryptoFramework.SymKey
let key = await generator.convertKey({ data: encryptKey })
//3.生成 iv等算法参数
let paramsSpec: cryptoFramework.IvParamsSpec = { iv: { data: iv }, algName: “IvParamsSpec” }
//4.通过指定算法名称，获取相应的Cipher实例
let aesCipher = cryptoFramework.createCipher(‘AES/CBC/NoPadding’)
//5.init cipher
await aesCipher.init(cryptoFramework.CryptoMode.ENCRYPT_MODE, key, paramsSpec)
//6.aes 加密
let encryptText = await aesCipher.doFinal({ data: content })
return encryptText.data
} catch (error) {
return new Uint8Array()
}
}
