Hello everyone,  
Does Processing have built-in functions, libraries or a simple way of encoding/decoding strings using a password?

Something like this:

```auto
encode('My String', password = 'mypass') //'ajdnfladfa739adl23'
decode('ajdnfladfa739adl23', password = 'mypass') // 'My String'

```

Thanks
