The “Change Encryption Key” function is used to generate a new AES encryption key. This is useful for redeploying a DataLocker to a new user, for example if a company needs to reissue a used DataLocker to a new employee, changing the encryption key will make all previously stored data unreadable.
Changing the encryption key is irreversible, and makes 100% of your data unreadable. Please use with caution.
