You say that my information is encrypted. What encryption does F-Secure use, and is F-Secure able to decrypt my information and hand it over to a third party?
At F-Secure, we use AES-256 encryption in CCM (counter with CBC-MAC) mode. We have no way of decrypting any information that you have saved. In addition, anyone using F-Secure Key is anonymous to F-Secure, so we have no way of identifying an individual user's data. So we never see any of your information at any stage, and therefore we can't decrypt it or hand it over to a third party.
Both the choice of encryption and anonymity of users were conscious decisions made to improve the security of the product and protect the privacy of our customers.
