We recommend supporting TLS 1.3, as it’s faster and more secure. If your app continues to use legacy TLS 1.0 or 1.1, please make plans to transition to TLS 1.2 or later. If your app has enabled App Transport Security (ATS) on all connections, no changes are required. These versions have been deprecated on Apple platforms as of iOS 15, iPadOS 15, macOS 12, watchOS 8, and tvOS 15, and support will be removed in future releases.
As part of ongoing efforts to modernize platforms, and to improve security and reliability, TLS 1.0 and 1.1 have been deprecated by the Internet Engineering Task Force (IETF) as of March 25, 2021. It provides confidentiality and integrity of data in transit between clients and servers exchanging information. Internet apps such as Safari, Calendar, and Mail automatically use this protocol to enable an. The TLS protocol supports both AES128 and AES256, and prefers cipher suites with forward secrecy.

Certificate pinning increases security, but limits your server team’s abilities to update their TLS certificates.Transport Layer Security (TLS) is a critical security protocol used to protect web traffic. iOS, iPadOS, and macOS support Transport Layer Security (TLS 1.0, TLS 1.1, TLS 1.2, TLS 1.3) and Datagram Transport Layer Security (DTLS). Use CertificatePinner to restrict which certificates and certificate authorities are trusted. It also assumes your HTTPS servers’ certificates are signed by a certificate authority. This strategy maximizes connectivity, but it is subject to certificate authority attacks such as the 2011 DigiNotar attack. java) ¶īy default, OkHttp trusts the certificate authorities of the host platform. This will increase security for usersĪnd increase connectivity with web servers.

This includes verification of the remote webserver with certificates and the privacy of data exchanged with strong ciphers.
That includes advanced hosts that run the latest versions of boringssl and less out of date hosts running older versions of OpenSSL.
