CredentialsJSON: The Definitive Playbook for Secure Credential Management
Key Takeaways
- CredentialsJSON is a standardized format for storing authentication tokens, API keys, and secrets in JSON structure
- Always encrypt credentials at rest and in transit using AES-256 or equivalent encryption
- Implement automatic rotation every 90 days or per your security policy
- Never commit credentialsJSON files to version control systems
- Use environment variables or secret managers for production deployments
- Validate schema compliance before processing credential data
What is CredentialsJSON?
CredentialsJSON is a structured format that standardizes how authentication credentials, API keys, certificates, and secrets are stored and transmitted in web applications. It provides a consistent schema that enables seamless integration across services while maintaining security best practices.
The format typically includes fields for:
- credential type (api_key, oauth_token, certificate, etc.)
- encrypted value or reference
- expiration timestamp
- metadata for rotation tracking
- scope and permissions
Implementation Checklist
Pre-Implementation Planning
- [ ] Define credential schema requirements
- [ ] Identify all services requiring credential access
- [ ] Establish rotation policy (recommend: 90 days)
- [ ] Select encryption standard (AES-256-GCM recommended)
- [ ] Document access control requirements
Development Phase
- [ ] Implement JSON schema validation
- [ ] Create encryption/decryption utilities
- [ ] Build credential rotation automation
- [ ] Add audit logging for all credential access
- [ ] Implement rate limiting on credential validation
Deployment Requirements
- [ ] Store credentialsJSON in secret manager (AWS Secrets Manager, Azure Key Vault, etc.)
- [ ] Configure automated rotation schedules
- [ ] Set up monitoring alerts for unusual access patterns
- [ ] Create rollback procedure for failed rotations
- [ ] Document incident response for credential compromise
Security Best Practices
Encryption Standards
Always use industry-standard encryption for credentialsJSON storage:
- At Rest: AES-256 encryption with KMS-managed keys
- In Transit: TLS 1.3 minimum
- Key Management: Use hardware security modules (HSMs) where possible
Access Control Implementation
| Role | Credential Access Level | Audit Requirement |
|---|---|---|
| Application Service | Read-only via secret manager | Mandatory |
| Developer | No direct access | N/A |
| DevOps Engineer | Rotation management only | Mandatory |
| Security Team | Audit and monitoring | Mandatory |
Rotation Procedures
- Automate rotation using scheduled jobs or secret manager features
- Maintain backward compatibility during transition periods
- Test rotation in staging before production deployment
- Keep previous credentials valid during graceful transition
- Immediately revoke compromised credentials
Common Pitfalls to Avoid
- Storing plaintext credentials: Never store unencrypted credentialsJSON files
- Hardcoding references: Avoid embedding credential paths directly in source code
- Over-permissioning: Grant minimum required access following principle of least privilege
- Ignoring expiration: Implement automatic expiry checking and alerting
- Manual rotations: Automate where possible to reduce human error
