Link Fingerprints Demo
"Link Fingerprints" is a scheme originally proposed by Gervase
Markham for embedding checksum information in links pointing to
files published for distribution. Please see LF
Info for more details about the "link fingerprints" concept, LF
syntax, and MDHashTool's LF-related features. This page serves as a
test matrix for, and demonstration of, the "link fingerprints" support
implemented in the MDHashTool extension.
