Security pattern of Oauth Token and Secret

I am working on an web application. Which uses oauth to authenticate from different services. Is there any risk of securing these tokens and secret开发者_运维问答 directly into database. Or should I encrypt them ?

What are the general security pattern for saving oauth token and secret

This thread answers all of your questions:

Securly Storing OpenID identifiers and OAuth tokens

Essentially, the following are dependent among themselves one or other way:

• Consumer key
• Consumer secret
• Access token
• Access token secret

Unless the consumer key/secret are also at risk, you don't need to encrypt the access token/secret. The access tokens can only be used in combination with the consumer key/secret which generated them.

I'm assuming you're talking about the typical "Service Provider," "Consumer" and "User" setup? If so, the session and cookies are good enough for saving tokens, but the problem is that it's your Consumers (your clients, as I understand) that need to be saving them and not you. Is there a session/cookie available in the scope of the calls to your API?

In either case, if the tokens are stored in the session or cookies, they will be "temporary" keys and the User will have to re-authenticate when they expire. But there is nothing wrong with that as far as the oAuth spec is concerned - as long as the Users don't mind re-authenticating.

Also bear in mind that the tokens are tied to a given service and user, and not to any IP address or device UUID, for example. They could not be used with different API and secret keys, as they are tied to the application they were issued for.

This way the user can de-authorize on a by-application basis, and every app can have a different set of permissions (e.g. read-only access). So your answer is you don't need to encrypt them, and you need them in plaintext anyway (if you're the User).
