How To Install Certificate On Ipad
Intro to certificate direction for Apple devices
Apple devices support digital certificates and identities, giving your organization streamlined access to corporate services. These certificates tin be used in a variety of ways. For instance, the Safari browser tin can check the validity of an X.509 digital certificate and institute a secure session with up to 256-bit AES encryption. This involves verifying that the site'south identity is legitimate and that communication with the website is protected to aid prevent interception of personal or confidential data. Certificates can besides be used to guarantee the identity of the author or "signer" and to encrypt postal service, configuration profiles, and network communications.
Using certificates with Apple tree devices
Apple devices include a number of preinstalled root certificates from various Certification Authorities (CAs), and iOS, iPadOS, and macOS validate the trust for these root certificates. These digital certificates can be used to securely identify a customer or server, and to encrypt the advice between them using the public and private fundamental pair. A certificate contains a public cardinal, data about the customer (or server), and is signed (verified) past a CA.
If iOS, iPadOS, or macOS can't validate the trust chain of the signing CA, the service encounters an error. A self-signed document can't be verified without user interaction. For more than information, see the Apple back up article Listing of available trusted root certificates in iOS xv, iPadOS 15, macOS 12, tvOS 15, and watchOS eight.
iOS and iPadOS devices can update certificates wirelessly if any of the preinstalled root certificates become compromised. You can disable this feature using the mobile device direction (MDM) brake, "Allow automatic updates to certificate trust settings," which prevents wireless certificate updates.
Mac computers can update certificates wirelessly or over Ethernet if any of the preinstalled root certificates become compromised. You can disable this feature using the mobile device management (MDM) brake, "Permit automatic updates to certificate trust settings," which prevents certificates updates over wireless or wired networks.
Supported identity types
A document and its associated individual cardinal are known every bit an identity. Certificates can be freely distributed, but identities must be kept secure. The freely distributed certificate, and especially its public primal, are used for encryption that can be decrypted only past the matching individual key. The private key role of an identity is stored every bit a PKCS #12 identity and (.p12) file and encrypted with another key that's protected by a passphrase. An identity can be used for authentication (such as 802.1X EAP-TLS), signing, or encryption (such as South/MIME).
The certificate and identity formats Apple tree devices support are:
-
Certificate: .cer, .crt, .der, X.509 certificates with RSA keys
-
Identity: .pfx, .p12
Certificate trust
If a certificate has been issued from a CA whose root isn't in the list of trusted root certificates, iOS, iPadOS, and macOS won't trust the certificate. This is often the case with enterprise-issuing CAs. To establish trust, use the method described in document deployment. This sets the trust anchor at the certificate being deployed. For multitiered public key infrastructures, information technology may be necessary to establish trust not only with the root certificate, but likewise with whatever intermediates in the chain. Often, enterprise trust is configured in a single configuration profile that can exist updated with your MDM solution as needed without affecting other services on the device.
Root certificates on iOS and iPadOS
Root certificates installed manually on unsupervised iOS and iPadOS devices through a profile display the following alert, "Installing the certificate "name of certificate" adds it to the list of trusted certificates on your iPhone or iPad. This certificate won't be trusted for websites until y'all enable information technology in Certificate Trust Settings."
The user can and so trust the certificate on the device by going to Settings > General > About > Document Trust Settings.
Note: Root certificates installed by an MDM solution or on supervised devices disable the option to change the trust settings.
