CA Mobile SDK (MAG/MAS) - SNI Client Support about ios-mas-foundation

[jhoongo]

Hi Marlos,

By default, if you are using iOS SDK, the SDK will validate the domain name of the certificate with the host that it is trying to reach.

You can refer to the actual implementation where it is creating the server trust with the domain name if validateDomainName is set to true (which is by default).

Please let me know if you have any further question or concern.

Thanks,

Hi,

I think you misunderstood my question. My question is if the HTTP Client libraries used by the SDK are SNI compliant.

When a request is made to a SNI-enabled server that hosts multiple HTTPS domains, the client must inform, during TLS handshake, the server name so the server can present the right SSL certificate corresponding to the domain accessed.

Client validation occurs after this part of the handshake.

I kindly ask you to read again the SNI description and the information my customer seeks in my original post.

Thanks again,

Marlos Chida

Hi Marlos,

Please find the below answer from Apple's official.

iOS MASFoundation's underlying network protocol is using NSURLSession, which according to Apple's official confirmed that NSURLSession, by default, will always use the host from the request URL for the SNI.

Please let me know if you have any further question or concern.

Thanks,

Hi,

That was exactly the answer I was looking for.
Thank you very much for your attention.
