While developing software, I am trying to store my valuable or sensitive items in a secure place to prevent easy access by unauthorized individuals. I could potentially store them in a
.env file, a Git variable, or some other location, but these methods can be easily accessed by others. So, I have been searching for a suitable solution, and guess what? I discovered a vault!
What is Vault??
A vault is essentially a highly secure storage space that is built to protect valuable or sensitive items. You can think of it as a specially designed room or container with strong walls, doors, and various security measures in place to prevent unauthorized access.Vault is a widely used open-source tool for securely managing secrets and sensitive data in modern software environments. It provides a secure storage and management solution for credentials, API keys, passwords, certificates, and other types of sensitive information.
Vault offers various features to enhance security, such as:
>. Secrets Management: Vault provides a secure API and command-line interface to manage secrets, allowing users and applications to store, retrieve, and delete secrets programmatically.
>. Dynamic Secrets: Vault can generate short-lived credentials on-demand for different systems and services. This approach reduces the risk of long-lived secrets being compromised.
>. Encryption as a Service: Vault offers encryption and decryption capabilities, enabling applications to encrypt data without directly accessing encryption keys. This helps to enforce separation of duties and enhances security.
>. Access Control: Vault provides fine-grained access control mechanisms, allowing administrators to define policies and permissions for different users, applications, or systems. This ensures that only authorized entities can access specific secrets.
>. Audit Logging: Vault maintains a detailed audit log of all actions performed on secrets, including read, write, and delete operations. This enables compliance with regulatory requirements and helps with security incident investigations.
>. Integration with Cloud Providers: Vault integrates with various cloud providers, allowing seamless integration with their native secrets management services and enhancing overall security in cloud environments.
In Python Vault can be implement using a hashicorp in following way?
pip install hvac
If you would like to be able to return parsed HCL data as a Python dict for methods that support it:
pip install "hvac[parser]"
client = hvac.Client(
# Login with username and password
response = client.secrets.kv.read_secret_version(
(response gives a items store in vau
VAULT_URL: ( this is a domain name or IP where we host our vault)
VAULT_USER: user_name to access a vault
VAULT_PASSWORD: password to access a vault
VAULT_ENV_PATH: path where we store our data
VAULT_SECRET_ENGINE_ENV: Vault main engine path
*note (We can also access a vault by token too and at first stage a vault is shield to unshield a vault we have to use our 4 token which we get while setting a vault)
If you are using a FASTAPI with a pydantic settings you can use a “pydantic-vault” which help you to setup your FASTAPI with pydantic Basesettings.
for reference go through pydantic-vault .
You can use a vault as per your need, it’s not necessary to use as i mention above, their is various method to implement it.
Here i have not mention how to set a vault , you can setup your vault as your need.
