Managing certificates in SAML metadata is often a headache. With multiple certificates to track, XML files to decode to check expiration dates, and formats that vary between providers (binary, base64), it’s easy to spend more time handling files than actually configuring your identity federation.
That’s exactly why I created SAML Cert Eye, a web application designed for administrators and engineers who regularly work with SAML metadata, both on the IdP and SP sides.
The service automatically analyzes X.509 certificates found in federation metadata. It displays their key details (subject, issuer, validity period, usages, fingerprints, etc.) and allows direct download in the desired format: binary (.cer, .der) or Base64/PEM. No more scripts or tools like openssl needed to convert or inspect certificates.
The goal is simple: save time and prevent errors when managing or renewing SAML certificates.
