Which database is best suited for making authenticated cross-domain JSON calls?

I have a vision to develop a userscript that can decrypt encrypted text depending on the user who created the text. To achieve this, I am looking to implement a database within the browser to store and retrieve decryption keys.

Imagine if Twitter user A wants to receive encrypted posts from Twitter user B. The userscript will prompt user A to authenticate in order to access the decryption keys stored in the database. Upon confirming that the post is from user B, the userscript will call upon the database to provide the necessary decryption keys for user B.

The ideal database should:

1. Require authentication for accessing user's keys
2. Come with a JavaScript API for easier integration
3. Be able to transmit decryption keys in JSONP format for cross-domain compatibility
4. Offer a sharing feature so that user A can share decryption keys with user B upon request

Do you know of any open-source databases that meet these criteria?

Answer №1

My current project focuses on implementing cross domain authentication within a complex system, enabling users to seamlessly maintain their login status across interconnected localized websites. As noted by Quassnoi, the challenge lies beyond database operations.

Personally, I have chosen to utilize .NET and Javascript for this task. The websites store data in XML format for localization purposes, with SQL serving as the centralized user database for universal access: storage and retrieval from any location. A quick search yields valuable resources: https://www.google.dk/search?q=asp.net+cross+domain+authentication

The versatility of .NET facilitates the creation of a customized webservice to handle encryption, decryption, and data transmission efficiently.

In terms of database options, obtaining a managed hosting account that supports MS SQL can be affordable, costing as little as $4 per month. Alternatively, opting for MySql along with a data connector can achieve similar functionality while saving on expenses.
