Hi all!
I have an ordinary, but easy, problem. Need to save public key into string
and load from this string.
Saving and loading are successed in the test code, but when I try to create
decryptor from mey new public key (which are loaded wrom string) - i had an
exception "Missing required parameter Primel1".
Wich parameter i need to add? What is the problem with this code?
In debug I see correct value inside all strings...
