Using encryption you can use a public and private key pair to encrypt your data or files. The public key will be used to encrypt the data and only the person having the private key and its passphrase will be able to decrypt that data. PGP encryption will be used for any data that has been as .
To enable PGP encryption you will need to set a PGP public on your survey. You may set different PGP public key for each of your survey adding on the way an additional layer of security.
You may set your public PGP key in the tab. Once you have entered your public key you can select the data classification to encrypt newly created survey respondents, text based answers or campaigns.
On-demand decryption let you enter your private PGP key to decrypt the data from the ngSurvey administration interface.
On-demand decryption will keep your private key alive in the browser memory for 5 minutes after which the key will be cleared and data automatically obfuscated again.
Your private key IS NOT stored permanently anywhere, however note that ngSurvey may need for some operations to send over the key to your server to decrypt the data but even in that case the key is never stored anywhere on the server and only used for duration of the operation. Make sure that SSL is enabled on your server if you wish to use that option.
Decryption of encrypted PGP data can be done either locally on your machine by and using a PGP decryption tool locally on your machine like or on-demand through the administration interface using our PGP decryption tool and your private key.
Here an example of a survey that has encrypted field answers that can be decrypted using the on-demand decryption.
