SSL Checker and HTTPS Test

The SSL FREAK Test checks whether your server is vulnerable to the FREAK attack (CVE-2015-0204) by accepting export-grade RSA cipher suites. FREAK was disclosed in 2015 and modern servers should have disabled export ciphers years ago — but legacy or poorly maintained servers occasionally still negotiate them, exposing TLS connections to a downgrade attack that breaks confidentiality. This test confirms your server refuses export-grade ciphers entirely.

What This Tool Checks

  • Server response to export RSA cipher offer
  • Server cipher suite list
  • TLS protocol versions supported
  • Cipher strength (RSA bit-length, ECDHE preferred)
  • Forward secrecy availability

Why It Matters for SEO

FREAK is now over a decade old, but unmaintained servers and embedded devices still occasionally accept export ciphers. A server that does silently downgrades client connections to a 512-bit RSA key — broken in hours on commodity hardware. Modern TLS configuration disables export ciphers entirely; this test confirms that disablement on your live server.

How to Fix It

Use a modern TLS cipher list (Mozilla SSL Configuration Generator is the standard reference). Explicitly disable EXPORT and DES ciphers. Patch the underlying OpenSSL / TLS library. Re-test after any config or library change.

How It Works

We open a TLS handshake offering export-grade RSA cipher suites. A vulnerable server accepts the offer and negotiates a weak connection; a properly configured server refuses with a handshake failure. The result is a binary pass / fail.

Common Mistakes to Avoid

  • Out-of-date OpenSSL version with export ciphers enabled
  • Embedded device or appliance with frozen TLS config
  • Custom cipher list copied from old documentation
  • Treating older CVEs as "fixed by default" without verifying
  • Server config changes that re-enable old ciphers accidentally

Quick Checklist

  • No export-grade ciphers accepted
  • Modern Mozilla cipher list applied
  • OpenSSL / TLS library up to date
  • TLS 1.2 + 1.3 only
  • Re-tested after every server config change
