What's the difference between Personal and Studio?

Personal ($39) is for one person — unlimited use on one active device at a time. Activate on a new device and the old one signs out. Studio ($199) is for teams and commercial client work — unlimited team members, early access to new tools, and a commercial license.

Do I need an account?

No. Use any tool free up to 5 times per day on compute-heavier tools, and unlimited on lightweight ones. No card, no account, no signup required.

Where are my files processed?

Right on your device. Files never upload to any server. Everything runs in your browser — you can verify in DevTools → Network.

What happens if I use my Personal license on a second device?

The new device activates and the old device signs out. Your license key stays the same — you just move it between devices as needed. No limit on how often you switch.

Does this work on my phone?

Yes. Every tool works on iPhone, Android, tablet, and desktop.

What if I want a refund?

30-day money-back guarantee on both tiers. No questions asked. Email sales@cipherforces.com.

Will you add more tools?

Yes. New tools ship regularly. Your license includes every tool we ever release — Studio members get early access.

SSL Certificate Checker

Check any website's SSL certificate and security headers.

Security Audit Headers Check HTTPS Verification

This checker inspects publicly-exposed TLS certificates. It is informational only and does not constitute a security audit. Domains you check are sent to our server to perform a standard TLS handshake; no other data is stored.

Domain Name

Enter a domain without protocol (e.g. example.com, not https://example.com)

Deep dive

About SSL Certificate Checker.

Check Any Website's SSL Certificate and Security Headers

Enter a domain and CipherForces SSL Checker reports the certificate issuer, expiry date, TLS version, cipher suite, and the full security-header profile (HSTS, CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy). Identifies weak configurations and gives grade.

Note: Unlike most of our tools, this one necessarily makes a server-side TLS handshake — browsers can't perform TLS-level introspection directly. The request is routed through our /api/ssl-check endpoint with SSRF protection (private IPs and loopback addresses blocked).

Common Use Cases

Pre-launch audit: Verify your site has valid HTTPS before going live.
Renewal reminders: Check how many days until your cert expires.
Vendor security review: Audit a third-party's HTTPS setup before integrating with them.
Compliance: PCI, SOC 2, and HIPAA require regular TLS audits.

Key Features

Certificate details: Issuer, subject, validity window, key strength.
TLS version + cipher suite: Flags deprecated TLS 1.0/1.1 or weak ciphers.
Security header grade: Scores HSTS, CSP, X-Frame-Options, etc. with remediation guidance.
Public-only: Only publicly-reachable domains are accepted — no internal networks.
