# KeyStore Files with Nethereum

Keep a private key on disk behind a password, and get it back

## What this does

A private key sitting in plain text is a problem, so the usual answer is to wrap it in a password-protected file. This shows you how to do that in .NET with Nethereum, using the standard Web3 Secret Storage keystore format, and how to unlock it again. Reach for it when a key has to be stored somewhere.

### Top 3 things it does for you

- Encrypt a private key with a password
- Open an existing keystore file
- Load an encrypted wallet in C#
