Operations

Obtain/Set Proxy Port

Go to Proxy -> Proxy Settings -> HTTP Proxy -> Port.

Configure SSL Proxying

Proxy -> SSL Proxy Settings -> SSL Proxying

and then list the target location you want to proxy for.

Examples:

• localhost.apple.com:443
• kibana.apps.openshift.novaordis.io:443

Export the Root Certificate

Exporting the root certificate is necessary when we proxy a Java application that sends HTTPS requests and we need Charles to be able to look inside those requests. All Java applications that use HttpClient will work based on this procedure.

To export: Help -> SSL Proxying -> Save Charles Root Certificate

Use the default format "Base 64 encoded certificate (.crt)".

The certificate thus saved can be used without any modification as part of the following procedure:

Configure a Java HTTP Client to Accept Self-Signed Certificates

Install Charles Root Certificate

Install the Root Certificate on Mac

Help -> SSL Proxying -> Install Charles Root Certificate.

This will install the self-signed root certificate in Keychain Access.

You will then need to navigate to it, select Trust then "When using this certificate Always Trust"

Install the Root Certificate in Chrome

1. Export the root certificate in ~tmp.

2. Go to Preferences -> Advanced -> Manage Certificates.

3. Go to the Trusted Root Certification Authorities tab. If on Mac, you will be sent to Mac Keychain Access. If Charles was previously used to "Install Charles Root Certificate", the root certificate should already be available there and there should be nothing else to do.
