Official guide: <https://docs.nubit.org/nubit-da/interact-with-nubit-da/manage-keys>

### Set Environment

Navigate to the nubit-node directory

```
cd nubit-node
```

Set the path and environment variables. Set `NODE_TYPE` to full if you are running a full node. In this case, we are running a light client

```
export PATH=$PATH:$(pwd)/bin
NETWORK=nubit-alphatestnet-1
NODE_TYPE=light
store=$HOME/.nubit-${NODE_TYPE}-${NETWORK}/
```

### List Keys

Use the following command to view your Nubit address list:

```
nkey list --p2p.network $NETWORK --node.type $NODE_TYPE
```

### Import Using M**nemonic Phrase** Into Nubit-Node

```
nkey add my_nubit_key --recover --keyring-backend test --node.type $NODE_TYPE --p2p.network $NETWORK
```

Enter your mnemonic phrase, when prompted with `"Enter your bip39 mnemonic,"`

### Import Using Private Key Into Nubit-Node

Nubit-node also supports importing addresses using private key files. Refer to the following command, replacing `my_nubit_key` with the desired key name and `~/nubit-da/nubit-node/account1.private` with the actual location of your private key file:

```
nkey import my_nubit_key ~/nubit-da/nubit-node/account1.private --keyring-backend test --node.type $NODE_TYPE --p2p.network $NETWORK
```

{% hint style="danger" %}
If you want to delete all your keys, run this command below:
{% endhint %}

```
rm -rf $HOME/.nubit-$NODE_TYPE*
```

{% hint style="danger" %}
If you want to delete specific keys, run this command below:
{% endhint %}

```
nkey delete (YOUR_KEY_NAME) --keyring-backend test --p2p.network $NETWORK --node.type $NODE_TYPE
```
