.NET Secure Memory Structures

Question

I know the .NET library offers a way of storing a string in a protected/secure manner = SecureString.

My question is, if I would like to store a byte array, what wou

Answer 1

There is no "best" way to do this - you need to identify the threat you are trying to protect against in order to decide what to do or indeed if anything needs to be done.

One point to note is that, unlike a string which is immutable, you can zero out the bytes in a byte array after you've finished with them, so you won't have the same set of problems that SecureString is designed to solve.

Encrypting data could be appropriate for some set of problems, but then you will need to identify how to protect the key from unauthorized access.

I find it difficult to imagine a situation where encrypting a byte array in this way would be useful. More details of exactly what you're trying to do would help.
