HarmonyOS SM2非对称加密生成ASN.1密文转C1C3C2标准密文出错

当前已经支持使用API去实现：参考：

//reslut 是加密后的密文数据
let spec: cryptoFramework.SM2CipherTextSpec = cryptoFramework.SM2CryptoUtil.getCipherTextSpec(reslut, 'C1C3C2');
/*
* C1 = spec.xCoordinate.toString(16) + spec.yCoordinate.toString(16)
* C2 = buffer.from(spec.cipherTextData).toString('hex')
* C3 = buffer.from(spec.hashData).toString('hex')
* */
let str = spec.xCoordinate.toString(16) + spec.yCoordinate.toString(16) + buffer.from(spec.cipherTextData).toString('hex') + buffer.from(spec.hashData).toString('hex')
