Hi,
I'm developing a Xamarin Forms app, and in iOS I want to create a RSA key-pair and be able to store the key-pair in the iOS KeyChain and retrieve the publicKey from iOS KeyChain anytime i want to. However i'm facing some problems due to the lack of documentation available on the internet about this issue.
So i created my RSA key pair this way, since i have to send the public key in DER format to a server (using BouncyCastle).

and then i need to store the keys on KeyChain but i can't find anything that helps me so i tried this way (byte[] value = RsaBytes):
$ ssh-keygen -t rsa -b 4096 -C '[email protected]' This creates a new ssh key, using the provided email as a label. Generating public/private rsa key pair. When you're prompted to 'Enter a file in which to save the key,' press Enter. This accepts the default file location.
First, i don't know if this is the best way to store anything is iOS KeyChain.
Second, when i get the 'ValueData' from KeyChain, i can't convert it back to a byte[] so i can't get my publicKey again anymore.
I get the key using the following method Asp net machine key generator.
and i try to convert it back to a byte[] that represents my public key using the following methods:

Add a description, image, and links to the rsa-key-pair topic page so that developers can more easily learn about it. Curate this topic Add this topic to your repo.
- Generate a new secret key. To generate the key, follow the same process as the one for generating a new private key. You use the Security library in each case. Import encrypted keys more securely. Android 9 (API level 28) and higher allow you to import encrypted keys securely into the Keystore using an ASN.1‑encoded key format.
How To Generate Rsa Key Pair
No one of them is the same as RsaBytes:
So, summing up all the problems
1 - I don't know the best way to create an RSA key pair in iOS and get publicKey DER-encoded (so I used BouncyCastle)
2 - Don't know how to store it properly on KeyChain
3 - I can access the information i stored, however it's useless since I can't convert it back to a publicKey
4 - When trying to access the information the user should be prompt to use TouchID, always.

I can't find samples of this in the internet.. I would really appreciate some help.
Many thanks to everyone.
