Fernet Encryption is a plugin that can be used to encrypt and decrypt data in WordPress using fernet.

## Description ##

Fernet Encryption is a plugin that can be used to encrypt and decrypt data in WordPress using fernet.

Development was originally sponsered by Access Networks.

# Setup your Key #

To setup your key, you need to add the following line to your wp-config file.

```
define( 'FERNET_KEY', 'YOUR_FERNET_KEY' );
```

If you choose not to setup your key, you will need to save a copy of the one provided upon activation of the plugin.

*IMPORTANT: Changing your WordPress salts will invalidate the default Fernet key provided.*

# How to Use #

To encrypt data simply use `$token = fernet_encrypt( 'YOUR MESSAGE' )` in your code.

To decrypt the data simply use `fernet_decrypt( $token )` in your code.

You can use the following shortcode to encrypt:

`[fernet-encrypt]YOUR MESSAGE[/fernet-encrypt]`

You can use the following shortcode to decrypt:

`[fernet-decrypt]YOUR-FERNET-TOKEN[/fernet-decrypt]`

We have also added useful helper functions:

 * fernet_get_post_meta
 * fernet_add_post_meta
 * fernet_update_post_meta
 * fernet_get_user_meta
 * fernet_add_user_meta
 * fernet_update_user_meta
 * fernet_add_option
 * fernet_get_option
 * fernet_update_option
