# Cloud KMS Signing with Nethereum

Sign transactions with keys you never have to hold

## What this does

Keeping a private key inside your application is the part everyone worries about. This signs Ethereum transactions using a key held in AWS KMS or Azure Key Vault instead, so your code asks for a signature rather than holding the key. Reach for it when a service needs to sign and you do not want the key in it.

### Top 3 things it does for you

- Sign a transaction with a cloud-managed key
- Move signing out of your app and into a key service
- Set up signing for a serverless wallet
