# `filebase64sha256` Function
2021-12-15 03:41:17 +01:00
`filebase64sha256` is a variant of [`base64sha256`](/language/functions/base64sha256)
that hashes the contents of a given file rather than a literal string.
This is similar to `base64sha256(file(filename))`, but

because [`file`](/language/functions/file) accepts only UTF-8 text it cannot be used to
create hashes for binary files.
