WSC Encryption Key
Create a strong encryption key
The encryption key is used to encrypt any data that end users place in the credentials form. The only way to see credentials is to provide the key to decrypt the information. Even anyone with access to your database cannot see any encrypted information. The only place the key is used is inside the WHMCS administration area. It's stored in hashed format. When creating an encryption key we advise you to use a website like Strong Random Password Generator (passwordsgenerator.net). Your key needs to be at least 16 letters and numbers long. These can be higher and lowercase but you cannot use special characters like @&*%^. Here a few examples of some strong strings.

Key Security
You must keep a copy of the encryption key you use. Without the key, any data in the database will become inaccessible. We advise you to keep your key on a USB stick in a locked safe. Do not store it on the server with WHMCS and we advise you don't store it in an email account or Cloud storage account. If you do, store it in a password-protected zip file.
If you ever disable WSC you will need to enter the same encryption key again to access any credentials attached to current open support tickets. All data collected is deleted when support tickets are closed.
