Why Choose This Project?

In modern applications, credentials, API keys, tokens, and certificates are everywhere. Hardcoding them in code or configs creates serious security risks. HashiCorp Vault provides a centralized way to securely store, access, and rotate secrets. This project ensures data protection, compliance, and secure communication in enterprise environments.

What You Get

• Centralized and secure storage of secrets.

• Dynamic secrets for databases and cloud resources.

• Automated key rotation to minimize exposure.

• Fine-grained access control for developers and services.

• Integration with DevOps pipelines & microservices.

Key Features

Technology Stack

Core Tool

• HashiCorp Vault – Secrets management

Integration Layer

• Spring Boot / Node.js / Python Apps – Fetch secrets dynamically

• Jenkins / GitLab CI / GitHub Actions – Secure CI/CD pipelines

• Docker & Kubernetes – Store cluster secrets securely

Optional Tools

• Consul / etcd – Service discovery & Vault backend

• Terraform – Infrastructure as Code with Vault secrets integration

Cloud Services Used (if deployed on cloud)

• AWS → IAM integration, AWS Secrets Engine in Vault

• Azure → Key Vault integration or Vault on AKS

• GCP → Google Cloud IAM + KMS integration with Vault

Working Flow

1. Application/service needs a secret (API key, DB password).

2. It authenticates with Vault using tokens, AppRole, or Kubernetes auth.

3. Vault checks policy & role-based permissions.

4. If authorized, Vault issues the secret (static or dynamic).

5. For dynamic secrets, Vault generates temporary credentials and revokes them after TTL expiry.

6. All actions are recorded in Vault’s audit logs.

Main Modules

1. Authentication Module → AppRole, JWT/Kubernetes Auth, Token-based Auth.

2. Secrets Engine Module → Store and generate secrets (KV, DB, AWS, TLS certs).

3. Encryption Module → Data encryption/decryption service.

4. Policy & Access Control Module → RBAC and ACL rules.

5. Audit & Monitoring Module → Logs for compliance & security tracking.

Security Features

• End-to-end encryption of secrets in transit & at rest.

• Dynamic credentials (never hardcoded).

• Automatic key rotation to reduce attack surface.

• Fine-grained RBAC with policies.

• Integration with HSM (Hardware Security Modules) for maximum security.

• Audit logs & compliance reporting.
