certificate thumbprint vs fingerprint

From this we can surmise that the thumbprint is some kind of hash or one way function (OWF), whose friendly name is thumbprint. In the screenshot to the right, we are looking at a certificate in Window’s certificate viewer that is showing its thumbprint. In fact – the thumbprint is not actually a part of the certificate.It’s calculated and displayed for your reference.

Sometimes applications ask for its fingerprint, which easier for work with, instead of requiring the X.509 public certificates (a long string). Windows) as a hash of the complete certificate (including the signature). This leads us to the conclusion that certificate fingerprints (MD5, SHA-1 or SHA-256 and others) are used as certificate identifiers which do not correlate with the certificate signature algorithm. Using the thumbprint in that way is safe as long as the thumbprint is computed with a cryptographic hash function that offers second-preimage resistance.
