## Encryption & Decryption using native .NET functions

## This is Symetrical encryption. Which means the same key is used to both encrypt and decrypt.

## The encryption method is based on AES 256bit.

## The major difference between this option and the ConvertFrom/To-SecureString functions
## is that this way produces much smaller encrypted files.
## I have not compared the 2 options in regards to performance though, as-in which one is faster.
