Decrypt password in Service

[AndreaSteyn]

Hi guys,

I have a password as a property on a thing.  I however need the password to run a service.

Where or how do I generate the key required to decrypt the password with the decrypt service in the EncryptionServices resource?

var result = Resources["EncryptionServices"].DecryptWithKey({

data: "" /* STRING */,
key: "" /* STRING */
});

Helpcenter section on password encryption should be useful here:

Hi @posipova ,

Thank you for the response.  

I read through the documentation but it appears that is for licence encrypting.  I want to use a user password in a service.  I want to figure out if there is a way to safely decrypt it as an administrator user to be able to use the password in a service.

The decrypt service needs a key which I am not sure how to generate.  Can you perhaps give any suggestions?

Hello @AndreaSteyn,

When you say "I want to use a user password in a service" you mean you want to use the password of a selected User entity? I'm not sure ThingWorx even stores user passwords, so there's nothing to decrypt, only hashes.

To clarify I want to create a password property that is not visible to all users for security.

I then need to use this password in a service to run a export service. So I therefore need to decrypt the password to be able to use it in the service.

I hope this provides more clarification.

use encrpt/decrypt with custom key.

use 128 bit key
