 - The client certificate fingerprint hash is now encoded using a URL-safe
-  version of the base64 algorithm (urlsafe_b64encode)[https://docs.python.org/3/library/base64.html#base64.urlsafe_b64encode].
+  version of the base64 algorithm [urlsafe_b64encode()](https://docs.python.org/3/library/base64.html#base64.urlsafe_b64encode).
