Mac Dev Center: URL Loading System: Using NSURLConnection. NSURLConnection provides the most flexible method of retrieving the contents of a URL. This class provides a simple interface for creating and canceling a connection, and supports a collection of delegate methods that provide feedback and control of many aspects of the connection. These classes fall into five categories: URL loading, cache management, authentication and credentials, cookie storage, and protocol support. Creating a Connection The NSURLConnection class supports three ways of retrieving the content of a URL: synchronously, asynchronously using a completion handler block, and asynchronously using a custom delegate object. To retrieve the contents of a URL synchronously: In code that runs exclusively on a background thread, you can call sendSynchronousRequest:returningResponse:error: to perform an HTTP request.
This call returns when the request completes or an error occurs. For more details, see “Retrieving Data Synchronously.” Making a POST Request. Mac Dev Center: NSURLProtectionSpace Class Reference. Overview An NSURLProtectionSpace object represents a server or an area on a server, commonly referred to as a realm, that requires authentication. The protection space defines a series of matching constraints that determine which credential should be provided. For example, if a request provides your delegate with an NSURLAuthenticationChallenge object that requests a client username and password, your app should provide the correct username and password for the particular host, port, protocol, and realm, as specified in the challenge’s protection space. Adopted Protocols copyWithZone: Instance Methods authenticationMethod Returns the authentication method used by the receiver.

Overview NSURLCredential is an immutable object representing an authentication credential consisting of authentication information specific to the type of credential and the type of persistent storage to use, if any.
The URL loading system supports three types of credentials: password-based user credentials, certificate-based user credentials, and certificate-based server credentials (used when verifying the server’s identity). When you create a credential, you can specify that it should be used for a single request, persisted temporarily (until your app quits), or persisted permanently (in the keychain). Class Methods credentialForTrust: Creates and returns an NSURLCredential object for server trust authentication with a given accepted trust. + (NSURLCredential *)credentialForTrust:(SecTrustRef)trust Parameters trust The accepted trust.

Fabian asks: I’m trying to request data from a website via HTTPS that does not have valid certificate. How can I ignore the certificate error? When the iPhone makes a HTTPS request it verifies that the certificate used to encrypt the data has a valid root certificate authority. Usually – for big sites – this is provided by Thawte or Verisign or any other recognized Root Certification Authority (CA). A bundle of the public certificates of such CAs is installed in the OS and enables the client to know which CAs are valid. The problem arises however if you don’t have the funds to purchase such a certificate from a CA, those are expensive.
When I googled for a solution it appears that Apple left out the possibility to ignore invalid certificates. If you do a simple synchronous URL request like below you will get no data but instead an NSError “untrusted server certificate”.

Last updated: July 02, 2016 | See all Documentation Let’s Encrypt uses the ACME protocol to verify that you control a given domain name and to issue you a certificate. To get a Let’s Encrypt certificate, you’ll need to choose a piece of ACME client software to use. We recommend that most people start with the Certbot client. It can simply get a cert for you or also help you install, depending on what you prefer. It’s easy to use, works on many operating systems, and has great documentation.
If certbot does not meet your needs, or you’d simply like to try something else, there are many more clients to choose from below, grouped by the language or environment they run in. The ACME clients below are offered by third parties. Bash GetSSL (bash, also automates certs on remote hosts via ssh) acme.sh (Compatible to bash, dash and sh) dehydrated (Compatible to bash and zsh) gheift/letsencrypt.sh Browser acme-client Docker Go HAProxy HAProxy ACME validation plugin Java nginx Node.js Perl Python Ruby Rust Windows.
Let's Encrypt - Free SSL/TLS Certificates. Certificate Decoder - Decode certificates to view their contents. Use this Certificate Decoder to decode your PEM encoded SSL certificate and verify that it contains the correct information. A PEM encoded certificate is a block of encoded text that contains all of the certificate information and public key. Another simple way to view the information in a certificate on a Windows machine is to just double-click the certificate file. You can use this certificate viewer by simply pasting the text of your certificate into the box below and the Certificate Decoder will do the rest.
Your certificate should start with "-----BEGIN CERTIFICATE----- " and end with "-----END CERTIFICATE----- ". Once you do the SSL install on your server, you can check to make sure it is installed correctly by using the SSL Checker. If you want to decode certificates on your own computer, run this OpenSSL command: openssl x509 -in certificate.crt -text -noout.
