What is certificate fingerprint used for?
A certificate thumbprint, also called a fingerprint, is a hash of a certificate, computed over all certificate data and its signature. Thumbprints are used as unique identifiers for cer- tificates, in applications when making trust decisions, in configuration files, and displayed in interfaces.
How do I find the fingerprint of a website?
Click the “Security” icon/tab at the top of the “Page Info” dialog. Click “View Certificate”. Verify that the certificate’s name under “Common Name (CN)” exactly matches what this GRC page shows. The SHA1 fingerprint is shown under “Fingerprints”.

WHAT IS fingerprint in SSL certificate?
A certificate’s fingerprint is the unique identifier of the certificate. A fingerprint is the MD5 digest of the der-encoded Certificate Info, which is an ASN. 1 type specified as part of the X. 509 specification. The Certificate Fingerprint is a digest (hash function) of a certificate in x509 binary format.
What is a SHA1 fingerprint?
A certificate’s fingerprint is the unique identifier of the certificate. Microsoft Internet Explorer calls it Thumbprint. The Certificate Fingerprint is a digest (hash function) of a certificate in x509 binary format. It can be calculated by different algorithms, such as SHA1 for Microsoft Internet Explorer.

Custom Site Fingerprinting In addition to the well-known web sites listed above, GRC’s web server can obtain and display the “fingerprint” of any HTTPS-capable public web server’s secure connection certificate.

If your web browser sees a different fingerprint for the same certificate (carefully verify the Certificate Name is identical) that forms strong evidence that something is intercepting your web browser’s secure connections and is creating fraudulent site certificates.
Which is easier to verify fingerprints or public keys?
Just verifying fingerprints is much easier than to verify a long public key. Another example is the so called self certifying file system. Here again only hashes of public keys get exchanged over a secure channel. (I.e. these hashes are embedded in URLs.)
Can a certificate be authentic if its fingerprint matches?
In the same way you wouldn’t and shouldn’t consider two objects to be equal just because their hash codes matched, you shouldn’t consider a certificate to be authentic just because its fingerprint appears in a list of “known certificate fingerprints”.
