About

The SSL Configuration Diff tool compares two TLS configuration snapshots and highlights the exact differences between them. It shows which cipher suites were added or removed, which protocol versions changed, and any modifications to security headers or certificate settings. This is essential for validating configuration changes and detecting unauthorized modifications.

The diff output is formatted as a clear side-by-side comparison with additions highlighted in green and removals in red, making it easy to understand exactly what changed between two configuration states.

How to Use

1Take a baseline snapshot of your current TLS configuration
2Make your configuration changes and take a second snapshot
3Run the diff comparison between the two snapshots
4Review the highlighted differences and verify only intended changes were made

Use Cases

•Change Validation: Verify that TLS configuration changes only modified what was intended
•Unauthorized Change Detection: Identify unexpected configuration modifications that may indicate compromise
•Migration Verification: Confirm server migrations preserved the exact TLS configuration
•Audit Evidence: Document configuration changes for compliance audits and change management records
•Drift Detection: Identify gradual configuration drift across servers in a load-balanced cluster

Tips & Best Practices

•Always take a snapshot before and after any TLS configuration change
•Store baseline snapshots in version control for complete change history
•Run diffs as part of your pre-deployment validation process
•Compare snapshots from multiple servers to detect configuration drift

Technical Details

●Comparison Scope: Protocols, cipher suites, certificate details, security headers, key parameters

●Output Format: Side-by-side diff with color-coded additions and removals

●Granularity: Individual cipher suite level comparison with security impact analysis

●Export: JSON diff data and human-readable report formats

Frequently Asked Questions

If the diff shows changes you did not make, investigate immediately. Check server access logs, review recent deployments, and verify the server has not been compromised. Unexpected TLS changes could indicate unauthorized access, misconfigured automation, or configuration drift from other teams.

Yes, you can compare any two snapshots regardless of which server they came from. This is useful for verifying that multiple servers in a cluster share identical configurations, or for comparing your configuration against a hardened reference.

The diff compares at the individual cipher suite level, protocol version level, and header level. For example, it will show if AES-128-GCM was replaced with AES-256-GCM, or if TLS 1.0 was disabled. Each change includes the security implication of the modification.
