# Overview

Cordial supports multiple methods to encode text strings with hashing algorithms. This is useful when passing sensitive information in URLs.

## Example

- [Set hash variable](https://support.cordial.com/hc/en-us/articles/115005855708-Hashing-algorithms#zp-1-0)
- [Print hash](https://support.cordial.com/hc/en-us/articles/115005855708-Hashing-algorithms#zp-1-1)
- [Rendered output](https://support.cordial.com/hc/en-us/articles/115005855708-Hashing-algorithms#zp-1-2)

```
{$hashed_email = $contact.channels.email.address|hash:"sha256"}
```

```
{$hashed_email}
```

The example above shows how the string `$hashed_email` is encoded using the `"sha256"` hashing algorithm.
