Errors

Possible errors when using data encryption:

  • library doesn't exists: PHP Sodium library have to be installed to be able to use data encryption feature. Here is a guide on how to install library: Sodium installation. If you don't want to use data encryption, you have to disable encryption in attribute settings.
  • wrong decryption key: decryption key has changed since data was last saved, so data can't be decrypted. The only way to decrypt data is to retrieve the original key from backup and replace the current decryption key with the original key.
