In Spring Boot, you can conceal passwords in a properties file by utilizing the spring.config.encrypt.enabled property. This property will allow you to encrypt sensitive data in your properties file, such as passwords. Here are the steps to conceal passwords:

  1. Generate a secret key: You can generate a secret key using the keytool command as shown below:

    keytool -genkeypair -alias mykey -keyalg RSA -dname "CN=Web Server,OU=Unit,O=Organization,L=City,S=State,C=US" -keypass mypassword -keystore keystore.jks -storepass mystorepassword
    
  2. Add the secret key to your application: You can add the secret key to your application by specifying the following in your application.properties file:

    encrypt.key-store.location=classpath:/keystore.jks
    encrypt.key-store.password=mystorepassword
    encrypt.key-store.alias=mykey
    encrypt.key-store.secret=mykeypassword
    

    This will specify the location of the keystore file and the password to access it. It will also specify the alias of the key to use and the password for that key.

  3. Encrypt your password: You can now encrypt your password using the encrypt command. For example, to encrypt the password mypassword, you can use the following command:

    java -jar myapp.jar --encrypt mypassword
    

    This will encrypt the password using the secret key specified in your application.properties file.

  4. Use the encrypted password in your properties file: You can now use the encrypted password in your application.properties file as shown below:

    mail.password={cipher}encrypted_password
    

    This will use the encrypted password in your application, and Spring Boot will automatically decrypt it using the secret key specified in your application.properties file.
