提示模块使用This encryption
密码出错了

const encrypted = crypto.publicEncrypt( { key: `MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDAW3P7gObqvIjJA3L7ZMVDdJ5lLis4jpShq14xWtS3AvnStWV4xY2BQ74bE08PvomByQc585vM7/HQNj2JNwQXwbjhyL5noC5Da3YGt5RiPMARa61LVeBcN8pipJNZoaFSrpMeG1CE45NMNhAnphv0WXzdX+9sr2uateIOi3Ab5QIDAQAB`, padding: crypto.constants.RSA_PKCS1_PADDING, }, Buffer.from(cardData), );

误差

Error: error:1E08010C:DECODER routines::unsupported at Object.publicEncrypt (node:internal/crypto/cipher:79:12)

我也这样试过，但还是一样的错误

const publicKey = Buffer.from(    'MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDAW3P7gObqvIjJA3L7ZMVDdJ5lLis4jpShq14xWtS3AvnStWV4xY2BQ74bE08PvomByQc585vM7/HQNj2JNwQXwbjhyL5noC5Da3YGt5RiPMARa61LVeBcN8pipJNZoaFSrpMeG1CE45NMNhAnphv0WXzdX+9sr2uateIOi3Ab5QIDAQAB',
      'base64',
    );
    const encrypted = crypto.publicEncrypt(
      {
        key: publicKey,
        padding: crypto.constants.RSA_PKCS1_PADDING,
      },
      Buffer.from(cardData, 'base64'),
    );

很奇怪，但是当我把钥匙放进一个文件里的时候，它就起作用了，但是我不明白为什么

然后读出来

const publicKey = fs.readFileSync('./rsaprivkey_public.key');
    const encryptedData = crypto.publicEncrypt(
      {
        key: Buffer.from(publicKey),
        padding: crypto.constants.RSA_PKCS1_PADDING,
      },
      Buffer.from(cardData),
    );
