Python Cron 작업에 대한 사용자 이름과 비밀번호를 안전하게 저장하는 방법은 무엇입니까?

<code class="python">import keyring

# Define a unique namespace for your application
service_id = 'IM_YOUR_APP!'

# Set the password for a given username
keyring.set_password(service_id, 'dustin', 'my secret password')

# Retrieve the password
password = keyring.get_password(service_id, 'dustin')</code>

<code class="python">import keyring

MAGIC_USERNAME_KEY = 'im_the_magic_username_key'

# Username to store
username = 'dustin'

# Store the password and username in the keyring
keyring.set_password(service_id, username, "password")
keyring.set_password(service_id, MAGIC_USERNAME_KEY, username)

# Retrieve username and password
username = keyring.get_password(service_id, MAGIC_USERNAME_KEY)
password = keyring.get_password(service_id, username)  </code>
