アプリケーションの内部ストレージから Android に証明書のピン留めを適用しようとしています。ファイル拡張子が .pfx の証明書があります。バンドルの raw フォルダーからファイルを読み込もうとすると正常に動作しますが、内部ストレージから読み込もうとすると、次のような例外が発生します。

java.io.IOException: ストリームが PKCS12 キーストアを表していません

私が使用している方法は次のとおりです。

fun generateSecureOkHttpClient(): OkHttpClient {
    var httpClientBuilder = OkHttpClient.Builder();

    try {

    // Create a simple builder for our http client, this is only por example purposes


    // Here you may wanna add some headers or custom setting for your builder

    // Get the file of our certificate
    var certFile = File(FilePath.getSSLCertificatePath()+"/sslCertificate.pfx");
    var caFileInputStream : InputStream = FileInputStream(certFile);


    //        var caFileInputStream = JobLogicApp.getContext().resources.openRawResource(R.raw.sslcert)

    //        val cert = ByteArray(certFile.length().toInt())
    //        caFileInputStream.read(cert)
    //        val targetStream: InputStream = ByteArrayInputStream(cert)

    // We're going to put our certificates in a Keystore
    val keyStore = KeyStore.getInstance("PKCS12")
    keyStore.load(caFileInputStream, "password".toCharArray())

    // Create a KeyManagerFactory with our specific algorithm our our public keys
    // Most of the cases is gonna be "X509"
    val keyManagerFactory = KeyManagerFactory.getInstance("X509")
    keyManagerFactory.init(keyStore, "password".toCharArray())

    val trustManagerFactory: TrustManagerFactory = TrustManagerFactory.getInstance(
        TrustManagerFactory.getDefaultAlgorithm()
    )
    trustManagerFactory.init(null as KeyStore?)
    val trustManagers: Array<TrustManager> = trustManagerFactory.getTrustManagers()
    check(!(trustManagers.size != 1 || trustManagers[0] !is X509TrustManager)) {
        ("Unexpected default trust managers:"
                + Arrays.toString(trustManagers))
    }
    val trustManager: X509TrustManager = trustManagers[0] as X509TrustManager


    // Create a SSL context with the key managers of the KeyManagerFactory
    val sslContext = SSLContext.getInstance("TLS")
    sslContext.init(keyManagerFactory.keyManagers, arrayOf<TrustManager>(trustManager), SecureRandom())

    //Finally set the sslSocketFactory to our builder and build it
    return httpClientBuilder
        .sslSocketFactory(sslContext.socketFactory, trustManager)
        .build()

    } catch (ex: Exception){
        ex.printStackTrace()
    }
    return httpClientBuilder.build();

}

誰かお願いします。前もって感謝します。そして sslCertificate.pfx はこの結果を与えます
