     6    The filesha256 function computes the SHA256 hash of the contents of
     7    a given file and encodes it as hex.

    16  `filesha256` is a variant of [`sha256`](./sha256.html)
    17  that hashes the contents of a given file rather than a literal string.
    18  
    19  This is similar to `sha256(file(filename))`, but
    20  because [`file`](./file.html) accepts only UTF-8 text it cannot be used to
    21  create hashes for binary files.
