使用的是下边的语句进行生成，参数都替换了

vendor/bin/CertificateDownloader.php -k ${apiV3key} -m ${mchId} -f ${mchPrivateKeyFilePath} -s ${mchSerialNo} -o ${outputFilePath}

返回的报错 Decrypting the input $ciphertext failed, please checking your $key and $iv whether or nor correct.

网上搜到的回答是apiV3key错误，可apiV3密钥自生成后就没动过，会和这个有关吗
