Click the Certificates folder to expand it. A certificate thumbprint is an hexadecimal string that uniquely identifies a certificate. The extended key usage extension must be absent or include the "web server authentication" and/or one of the SGC OIDs. 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. Returns a string containing the calculated certificate fingerprint as lowercase hexits unless raw_output is set to TRUE in which case the raw binary representation of the message digest is returned. Once OpenSSL is installed, we can use it to create the certificate. SSL Certificate provides security for your website by encrypting communications between the server and the person visiting the website. bat The thumbprint is used to quickly determine if a presented certificate is the same as another certificate, such as the certificate that was accepted previously. You can get it with -fingerprint flag of openssl x509, for example, or using any hash calculation tool.
