# `filebase64sha256` Function
`filebase64sha256` is a variant of [`base64sha256`](./base64sha256.html)
that hashes the contents of a given file rather than a literal string.
This is similar to `base64sha256(file(filename))`, but
because [`file`](./file.html) accepts only UTF-8 text it cannot be used to
create hashes for binary files.
