# Encrypt passwords

NebulaGraph Exchange supports using encrypted passwords in [NebulaGraph Database Developer Edition configurations](https://dev-docs.nebula-graph.io/v5.3.2/utilities/exchange/config/#database_configurations) for enhanced security during data import. This topic introduces how to generate encrypted passwords and use them in the configurations.

## Prerequisites

NebulaGraph Exchange is deployed. For more information, see [Deploy NebulaGraph Exchange](https://dev-docs.nebula-graph.io/v5.3.2/utilities/exchange/deploy-exchange/).

## Steps

1. 

Go to the installation directory of NebulaGraph Exchange, such as `nebula-graph-exchange/` and run the following command to encrypt your password:

````
java -jar cli-5.3.0.jar -e -password "<your_password>"

````

Replace `<your_password>` with the password you want to encrypt. If the password contains shell special characters such as `$`, wrap it in quotes according to your shell. For example:

````
java -jar cli-5.3.0.jar -e -password "Yueshu456$"

````

The encrypted password is returned along with a public key and a private key.

2. 

Set the environment variable `EXCHANGE_PRIVATE_KEY` to the private key. For example:

````
export EXCHANGE_PRIVATE_KEY=<your_private_key>

````

Replace `<your_private_key>` with the private key value returned in the previous step.

3. 

Set `enableEncryptPasswd` to `true` and `passwd` to the encrypted password in [NebulaGraph Database Developer Edition configurations](https://dev-docs.nebula-graph.io/v5.3.2/utilities/exchange/config/#database_configurations). For example:

````
taskType: import
nebula: {
    graphAddr: "127.0.0.1:9669,127.0.0.1:9670"
    graphName: "movie"
    user: "root"
    enableEncryptPasswd: true
    passwd: "<your_encrypted_password>"
    schema: "/default_schema"
    ...
}

````

Replace `<your_encrypted_password>` with the encrypted password.
