| # `filesha256` Function |
| |
| `filesha256` is a variant of [`sha256`](/language/functions/sha256) |
| that hashes the contents of a given file rather than a literal string. |
| |
| This is similar to `sha256(file(filename))`, but |
| because [`file`](/language/functions/file) accepts only UTF-8 text it cannot be used to |
| create hashes for binary files. |
