    10  # `filesha256` Function
    11  
    12  `filesha256` is a variant of [`sha256`](./sha256.html)
    13  that hashes the contents of a given file rather than a literal string.
    14  
    15  This is similar to `sha256(file(filename))`, but
    16  because [`file`](./file.html) accepts only UTF-8 text it cannot be used to
    17  create hashes for binary files.
