| # `filebase64sha512` Function |
| |
| `filebase64sha512` is a variant of [`base64sha512`](/language/functions/base64sha512) |
| that hashes the contents of a given file rather than a literal string. |
| |
| This is similar to `base64sha512(file(filename))`, but |
| because [`file`](/language/functions/file) accepts only UTF-8 text it cannot be used to |
| create hashes for binary files. |
