--- page_title: filebase64sha512 - Functions - Configuration Language description: |- The filebase64sha512 function computes the SHA512 hash of the contents of a given file and encodes it with Base64. --- # `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.
