1. Interaction between security components and Istio control plane.
  1. Validation of mutual TLS (mTLS) configurations.
  1. Testing of JWT token validation and RBAC policies.
  1. Validation of certificate management and rotation.
- **Setup**: The main test setup in this folder initializes the Istio control plane with security configurations.

## Adding a New Integration Test

        .build()
    val handshakeCertificates =
      HandshakeCertificates.Builder()
        .heldCertificate(heldCertificate)
        .addTrustedCertificate(heldCertificate.certificate)
        .build()

    client =
      client.newBuilder()
        .sslSocketFactory(
          handshakeCertificates.sslSocketFactory(),
          handshakeCertificates.trustManager,
        )

Prior to 1.17 and for existing nodes created by `kubeadm init` where kubelet client certificate rotation is desired, you must modify `/etc/kubernetes/kubelet.conf` to point to the PEM symlink for rotation:

  /**
   * Returns true if the host and port are unchanged from when this was created. This is used to
   * detect if followups need to do a full connection-finding process including DNS resolution, and
   * certificate pin checks.
   */
  fun sameHostAndPort(url: HttpUrl): Boolean

  /**
   * A plan holds either an immediately-usable connection, or one that must be connected first.

          // TLSv1.2 Events
          // Produced ClientHello handshake message
          // Consuming ServerHello handshake message
          // Consuming server Certificate handshake message
          // Consuming server CertificateStatus handshake message
          // Found trusted certificate
          // Consuming ECDH ServerKeyExchange handshake message
          // Consuming ServerHelloDone handshake message

OkHttp 2.x Change Log
=====================

## Version 2.7.5

_2016-02-25_

 *  Fix: Change the certificate pinner to always build full chains. This
    prevents a potential crash when using certificate pinning with the Google
    Play Services security provider.


## Version 2.7.4

_2016-02-07_

 *  Fix: Don't crash when finding the trust manager if the Play Services (GMS)
    security provider is installed.

  privateKey: private.key
