# Sha512

{% hint style="info" %}
The **`Sha512()`** function hashes a specified text string with SHA512, and returns a hexadecimal text string. This hash function is preferred to SHA-256, being more secure.

WIKI: <http://en.wikipedia.org/wiki/SHA-2>

This function is NOT SQL compatible. For more information about SQL compatibility, see our [documentation](/platform/wemreference/sql-compatibility.md).

*Hashed values cannot be decoded, usually you check an incoming value against a known value that you hash yourself and check if both values are identical, to verify correctness without knowing the actual value.*

*If you save this value to a database field make sure this field length is more then 128 digits, to make sure the whole string is saved.*&#x20;
{% endhint %}

{% hint style="success" %}
Returns a hexadecimal text string.\
Returns <mark style="color:red;">**`Unknown`**</mark> if one of the parameter values is unknown or outside the common valid boundaries.
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wem.io/platform/wemreference/functions/security/sha512.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
