使用PKCS8 RSA256算法编码JWT在JWT.IO上，但不在应用中

Question

我尝试在Swift 4中实现JWT时有问题。我使用JWT.IO的JWT库。我正在尝试使用PKCS8 PEM Filetype和RSA256算法证书加密有效载荷。但是始终使用消息"无法完成操作。

有人可以帮我吗？

代码：

let payload: [AnyHashable:Any] = ["payload":"hiden_information"]
let algorithmName = "RS256"
let path = Bundle.main.path(forResource: "priv", ofType: "pem")
let privateKeySecretData = try? Data(contentsOf: URL(fileURLWithPath: path!))
let privateKey = String(data: privateKeySecretData!, encoding: .utf8)!
let signDataHolder: JWTAlgorithmRSFamilyDataHolder =  JWTAlgorithmRSFamilyDataHolder()
 _ = signDataHolder.keyExtractorType(JWTCryptoKeyExtractor.privateKeyWithPEMBase64().type)
_ = signDataHolder.algorithmName(algorithmName)
_ = signDataHolder.secret(privateKey)
let signBuilder : JWTEncodingBuilder = JWTEncodingBuilder.encodePayload(payload)
_ = signBuilder.addHolder(signDataHolder)
let signResult = signBuilder.result
        if ((signResult?.successResult) != nil) {
            print(signResult!.successResult.encoded)
        } else {
            print(signResult?.errorResult.error.localizedDescription ?? "Unknown")
        }

jwt版本3.0.0.-beta7未使用PKCS8。我将PKCS1与RSA256一起使用！

 func encryptPayload(payload:[AnyHashable:Any])->String?
{
    var resultStr: String?
    var publicKeyCrypto: JWTCryptoKeyProtocol? = nil
    do {
        publicKeyCrypto = try JWTCryptoKeyPublic(pemEncoded: AppConstant.Scurity.publicKey, parameters: nil)
    }
    catch {
        NSLog("error: (error)")
    }
    guard let theCrypto = publicKeyCrypto else {
        return nil
    }
    do {
        let privateKeyCrypto = try JWTCryptoKeyPrivate(pemEncoded: privateKey, parameters: nil)
        guard let holder = JWTAlgorithmRSFamilyDataHolder().signKey(privateKeyCrypto)?.secretData(AppConstant.Scurity.privateKey.data(using: .utf8))?.algorithmName(JWTAlgorithmNameRS256) else {return nil}
        let headers : [AnyHashable:Any] = ["alg": "RS256","typ": "JWT"]
        guard let encoding = JWTEncodingBuilder.encodePayload(payload).headers(headers)?.addHolder(holder) else {return nil}
        let result = encoding.result
        print(result?.successResult?.encoded ?? "Encoding failed")
        print(result?.errorResult?.error ?? "No encoding error")
        let verifyDataHolder = JWTAlgorithmRSFamilyDataHolder().signKey(theCrypto)?.secretData(publicKey.data(using: .utf8)!)?.algorithmName(JWTAlgorithmNameRS256)
        let verifyResult = JWTDecodingBuilder.decodeMessage(result?.successResult?.encoded).addHolder(verifyDataHolder)?.result
        if verifyResult?.successResult != nil, let result = verifyResult?.successResult.encoded {
            print("Verification successful, result: (result)")
        } else {
            print("Verification error: (verifyResult!.errorResult.error)")
        }
        resultStr = result?.successResult.encoded
    } catch {
        print(error)
    }
    return resultStr
}
