do not save encrypted pages to disk registry

If any of these were not implied in your question then it make no sense.Ī competent programmer will use session cookies, random identifiers and server side data in the right mix to protect the application it would be dangerous to make assumptions about the implementation details of browser not specifically documented as requirements. It pre-supposes that cookies will be written to disk (not necessarily) and that the browser and OS do not enforce strict locking or that the cookie persists between browser sessions.

The contents of the cookie may already have been encrypted elsewhere. This statement only makes any sense if you are suggesting that that data sent by a server in the form of a cookie should be encrypted by the browser before being committed to non-volatile storage. If cookies are stored in plaintext, then any program which has read access to the cookie file can hijack the browser session This should be a comment, but its a bit long. Thus encrypted cookies make web sites suspicious. Users think that the web site is collecting some information that the users might not like and makes this information unreadable for user. Server will receive correct cookies, decrypt them an will not be able to distinguish, if cookies come from you or from attacker.Įncrypted cookies have a huge disadvantage, because they make for user impossible to check what information is saved in the cookies. When an attacker gets access to your file with cookies, he can copy them and use in the browser. That is why in a application with good architecture client logic does not depend on cookies contents and thus client does not need decryption of cookies.Įncrypted cookies give normally false feeling of security. If that doesn't solve your issue, along with checking it on another computer, check the Properties of the Flash drive & see what it says. client makes an AJAX or REST call and retrieves needed information from the server. Type 'Services' into the Start Menu (w/o the quotes), go down the list, you'll see 'BitLocker Drive Encryption' as a Service. Any data that client needs is normally delivered either within the content (HTML, CSS, JavaScript) or by a service call, e.g. Now storage is relatively cheap and for many web sites the amount of storage for cookies even for millions of clients is not a big problem.Ĭlient code in a good application normally doesn't have logic that depends on information in cookies. It was more important at the beginning of Internet. Identification via other means (user agent, screen resolution, canvas fingerprint etc.) might identify the client, but not 100% reliable.Ģ. Signing in at every possible web site is impossible. Without cookies server would have to deal with following problems:ġ.

The primary purpose of cookies is to store client information for server.
