Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

IPP ERROR: Application exception: System.Security.Cryptography.CryptographicException: Invalid provider type specified.

Hey guys,

I'm trying to get into Mobile Development with UE, but am already struggling with the baby steps. I've done everything according to the available guides, but seem to be unable to deploy my game from Unreal directly onto the attached iPhone (I'm trying to deploy from a Windows 10 machine to iPhone SE with UE4.15.1).

I went through the whole process using the IPP to create certificate request, key pair getting the provision from the Apple Developer platform, create an App ID and the signing certificate there and so on. All seems to be working fine, inside UE4 both Provision and Cerificate turn green and show valid (inside IPP I never saw any green checkmarks though), but when I try to launch an All_IOS it always fails to deploy.

"PackagingResults:Error: Error Deployment failed! Unknown Error"

It seems to get stuck here: "IPP ERROR: Application exception: System.Security.Cryptography.CryptographicException: Invalid provider type specified." and I couldn't find out what causes this. Apologies if that turns out to be an amateur question, but as mention I'm new to the mobile sector.

I did try the same process with just the standard RollingExample map and run into the same error, so it seems either I'm doing something wrong or something is wrong with my machine setup.

Any hints to point me in the right direction would be greatly appreciated!

Just following up on this:

I haven't solved the issue yet, even after additional research and trying out every solution I found in the forums.

Nevertheless: Following exactly the same process, but instead of using my workstation I used my Surface Book this time, it finally deployed everything successfully on the first go. So it seems like there is some sort of security issue going on using my workstation for the ios build.

You can deploy your game from your Surface Book to the iPhone? You are running Unreal 4 on your Surface Book? Could you provide your Surface Books DXDiag as well as your work stations DXDiag?

Looking over similar AnswerHub posts a few people have corrected this issue by typing the correct Bundle Identifier in Project Settings>iOS. Since this has been successful from your Surface Book, I suggest you copy your Project Settings from your Surface and making sure they Match what you have on your Workstation.

Let me know if the settings are identical and the issue still occurs on your Windows 10 system. Please include the requested dxdiags when you respond.
