Thank you a lot!
It works for me!
I had a tab bar controller. When the imagePicker with camera disappeared from the screen, the item from the TabBar was also deleted.
You solved it ^_^

Yeah
For P256
We have 1 header byte
32 bytes of x
32 bytes of y
32 bytes of K (private key)
Total - 97 bytes
For Public key - 65 (without K)
The problem is to create from 32 bytes of private key (rawRepresentation) these 97 bytes
I found solution with this library
Unfortunately counting of KeyPair takes a lot of time
But the code is open and it's very cool.
