# `base64sha512` Function
|
|
|
|
`base64sha512` computes the SHA512 hash of a given string and encodes it with
|
|
Base64. This is not equivalent to `base64encode(sha512("test"))` since `sha512()`
|
|
returns hexadecimal representation.
|
|
|
|
The given string is first encoded as UTF-8 and then the SHA512 algorithm is applied
|
|
as defined in [RFC 4634](https://tools.ietf.org/html/rfc4634). The raw hash is
|
|
then encoded with Base64 before returning. Terraform uses the "standard" Base64
|
|
alphabet as defined in [RFC 4648 section 4](https://tools.ietf.org/html/rfc4648#section-4).
|

|
|
## Examples
|
|
|
|
```
|
|
> base64sha512("hello world")

|
* [`filebase64sha512`](./filebase64sha512.html) calculates the same hash from
|
|
the contents of a file rather than from a string value.
|
|
* [`sha512`](./sha512.html) calculates the same hash but returns the result
|
|
in a more-verbose hexadecimal encoding.
