So we can query openssl with this command: SSL_CERT_DIR="" openssl s_client -connect imap.mail.me.com:993 < /dev/null 2>/dev/null | openssl x509 -fingerprint -noout -text -in /dev/stdin The output can be quite long for some pages but we are only intereseted in the first lines which look like. openssl1: If you are logged in to the vIDM host in a console or using SSH, run the following command to get the thumbprint: openssl1 s_client -connect :443 < /dev/null 2> /dev/null | openssl x509 -sha256 -fingerprint -noout -in /dev/stdin OpenSSL: Check SSL Certificate – Additional Information Besides of the validity dates, an SSL certificate contains other interesting information. openssl s_client verify. I'm having a somewhat odd issue. The curve objects have a unicode name attribute by which they identify themselves.. I was looking for a script that can extract fingerprint from any SSL certificate provided you have the URL. The basic and most popular use case for s_client is just connecting remote TLS/SSL website. Hence in your test the openssl s_client command advertises that is supports NPN but the server turns a blind eye onto ot. use OpenSSL to get the public certificate for a website using the steps in my article Extracting SSL/TLS Certificate Chains Using OpenSSL, I've found that the requests I send sending are just timing out. Each SSL certificate contains the information about who has issued the certificate, whom is it issued to, already mentioned validity dates, SSL certificate’s SHA1 fingerprint and some other data. And there it was! I have found couple of them but non of them did what I expected exactly so I decided to write my own based on what I have found. If I use $ echo | openssl s_client -servername google.com -connect google.com:443 |\ sed -ne ‘/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p’ > certificate.crt In osx high Sierra I got “sed command not found”. Check TLS/SSL Of Website.

To get the SHA256 fingerprint, you'd do: openssl x509 -in CERT.pem -noout -sha256 -fingerprint. Step 3: Try to verify the digital certificate again, but this time make use of the previously downloaded certificate ("USERTrustLegacySecureServerCA.crt").. Before using the downloaded certificate, we need to convert it to the PEM format (not required this time; exemplified later), and build the certificates directory required by the openssl "-CApath" option. // Parse cmdline arguments using flag package, // Get the ConnectionState struct as that's the one which gives us x509.Certificate struct, how to enable JavaScript in your web browser, ← Fetch certificates and private keys bundle from Azure Keyvault in Go via Azure SDK, To create a TLS connection, we'll be using. Although Im pretty sure I have it installed, as if I run just “sed” it is listed there. The fingerprint/thumbprint is a identifier used by some server platforms to locate the certificate in a certificate store. You can generate a MD5 fingerprint for a SHA2 certificate. Fingerprint is a great way to get a "hash" for a specific version of certificate. So, we need to get the DER (Distinguised Encoding Rules) encoded bytes and use that as the data to get the md5 hash. The following command shows detailed server information, along with its SHA256 fingerprint: $ echo | openssl s_client -connect www.feistyduck.com:443 2>&1 | openssl x509 -noout ↩ -text -fingerprint -sha256.
