# `base64sha512` Function
`base64sha512` computes the SHA512 hash of a given string and encodes it with
2018-05-23 18:16:42 +02:00
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")

* [`sha512`](./sha512.html) calculates the same hash but returns the result
in a more-verbose hexadecimal encoding.
