How to save the secret key?

Question

Programming

You need to store a string with a secret key in a C# application. What other ways are there besides hardwiring the key into the code and then using an obfuscator?

Answer 1

If you are working with System.Security.Cryptography, read about the CspParameters class and the KeyContainerName property. Everything has been thought of before us.

Answer 2

split the key into a char array, initialize the array elements in different places of the code (but it is important that the compiler does not optimize this) for search complexity,
and use ProtectedMemory
