--- layout: "language" page_title: "filesha512 - Functions - Configuration Language" sidebar_current: "docs-funcs-crypto-filesha512" description: |- The filesha512 function computes the SHA512 hash of the contents of a given file and encodes it as hex. --- # `filesha512` Function -> **Note:** This page is about Terraform 0.12 and later. For Terraform 0.11 and earlier, see [0.11 Configuration Language: Interpolation Syntax](../../configuration-0-11/interpolation.html). `filesha512` is a variant of [`sha512`](./sha512.html) that hashes the contents of a given file rather than a literal string. This is similar to `sha512(file(filename))`, but because [`file`](./file.html) accepts only UTF-8 text it cannot be used to create hashes for binary files.
