你可以通过AsyKeyGenerator.convertKey方法将RSA或者SM2私钥转为KeyPair对象。参考文档:https://developer.huawei.com/consumer/cn/doc/harmonyos-refere...示例代码如下:import crypto from '@ohos.security.cryptoFramework'; /** * 将非对称加密字符串priKey转换为symKey对象 * @param privateKey字符串key * @param symAlgName 秘钥规格 * @returns */ static async convertPriKeyFromStr(privateKey: string, symAlgName: string) { let symKeyBlob: crypto.DataBlob = { data: StrAndUintUtil.stringToByteArray(privateKey) }; let aesGenerator = crypto.createAsyKeyGenerator(symAlgName); let symKey = await aesGenerator.convertKey(null, symKeyBlob); return symKey; } /** * 字符串转换为Uint8Array数组 * @param str 字符串 * @returns Uint8Array数组 */ static stringToByteArray(str: string): Uint8Array { const hexString = str.match(/.{1,2}/g); // 将字符串按每两个字符分割为数组 let arr = new Array<string>(); hexString?.forEach((val) => { arr.push(val); }) const byteArray: number[] = arr.map(byte => parseInt(byte, 16)); // 将每个十六进制字节转换为整数 return new Uint8Array(byteArray); }
