Fingerprint
Usage
Fingerprinting and SRI can be applied to any asset file using resources.Fingerprint
which takes two arguments, the resource object and an optional hash algorithm.
The default hash algorithm is sha256
. Other available algorithms are sha384
and (as of Hugo 0.55
) sha512
and md5
.
Any so processed asset will bear a .Data.Integrity
property containing an integrity string, which is made up of the name of the hash algorithm, one hyphen and the base64-encoded hash sum.
{{ $js := resources.Get "js/global.js" }}
{{ $secureJS := $js | resources.Fingerprint "sha512" }}
