High strength symmetric encryption for your favorite email, plus real-time secure chat ⚠️ NOTICE: THIS EXTENSION HAS EVOLVED INTO PRIVACY BAR ⚠️ This legacy standalone tool is no longer actively maintained. The exact same functionality has been integrated, upgraded, and fully secured inside our flagship extension: Privacy Bar. Looking for pure Symmetric Encryption? Privacy Bar handles it entirely offline and has multiple modes in addition to what URSA offers. Looking for Read-Once payloads? Privacy Bar generates self-destructing messages out of the box. Looking for Page Isolation/Sandboxing? Privacy Bar features an enhanced, isolated "Safe Space" tab. 👉 Search the Chrome Web Store for "Privacy Bar" or visit privacybar.net to upgrade to the complete, modern suite. URSA sits near your tray bar to provide secure and easy symmetric encryption of text, images, and files. This is the process: 1. Click the bear icon to load URSA into a new tab. 2. Type the secret key into the top box. The recipient must know this key. 3. Type your message, possibly containing rich formatting, images, and even files into the large box, then click Encrypt. The recipient will decrypt the encrypted message, which can be sent by email or some other means without fear of its being decrypted, by typing the same key, pasting the encrypted message, and clicking Decrypt. If you feel really paranoid, URSA can encrypt into a cover image, so that it cannot be detected that anything is there. The image looks the same after the secret data have been injected. If you find yourself exchanging frequent messages with someone, you can switch into real-time chat, which can include text, files, audio, and even video! URSA's main encryption algorithm is XSalsa20, included within the NaCl encryption library. This algorithm has extensively been vetted by experts for over ten years without flaws being found. There are also two experimental algorithms: Pad, which uses a large piece of text (from a book, or a webpage) as key and is theoretically unbreakable, and Human, which can be performed by hand if necessary. URSA is fully compatible with PassLok Privacy, its larger sibling, also in this Web store. PassLok adds several asymmetric encryption modes, as well as secret splitting and digital signatures. There is also a web app at https://passlok.com/ursa You can check the integrity of the web version of URSA with this data: Current version of URSA is: 4.3 SHA256 of the single-file version, which can be downloaded from the above link: 62ac-893d-a6df-edfc-dbd9-a849-5404-5b13-6701-d0da-87c2-8d0b-bc44-5153-742b-96b0 See the developer reading this on video: https://www.youtube.com/watch?v=nzTyfvgrHgc

Encryption Tool
Encrypt and decrypt text and files with SHA-256 algorithm; store and sync encrypted textual data. This extension enhances your right-click context menu for text selections with the following options: 1. Securely copy selected text to the clipboard with encryption. 2. Encrypt selected text and securely save it in synchronized storage. 3. Replace the original content with encrypted text. In addition, it offers the ability to: 4. Decrypt encrypted text and copy it to the clipboard. 5. Decrypt encrypted text and replace the original content. Important details about the extension: - The extension uses your passphrase to generate a new SHA-256 private key and a random public key for text encryption and decryption. - Please remember your passphrase, as there is no way to recover encrypted text if it is forgotten. For your privacy, the extension does not store passphrases. - You can choose to store encrypted content in your browser's synchronized storage for easy access across synced browsers. - You can also encrypt and decrypt binary files in bulk with this extension too. It stores the converted files to the default download directory of your browser. Some use cases for this extension include: 1. Safely encrypting passwords when sending emails. 2. Privately archiving important data. 3. Securely transmitting sensitive information, like passwords, to another device. Privacy assurance: This extension operates entirely offline, ensuring no data is sent to any external server.
WebAPI Blocker
Easily block (nullify) undesired Web API(s) and improve your privacy. WebAPI Blocker is a lite addon that lets you easily block and nullify a desired web API. Simply open the toolbar popup UI and choose an API from the drop-down list (top left side). Then, click on the (+) button to add the item to the API list. Once you add an item, you can remove it from the list by clicking on the "remove" button next to each item. Moreover, you can deactivate an item by removing the checkmark from the list. There is also a "reload" button at the top toolbar to reload the active tab. On the right side, you can add desired domains to the whitelist table. Please enter a domain name in the input field and then click on the (+) sign to add it to the table. To remove a domain, please click on the cross sign next to each item. Note: please be careful when you block (nullify) a web API. Because certain API(s) may cause websites to not fully load or even make them unresponsive. Therefore, please do enough research before disabling an API. To report bugs, please fill the bug report form on the addon's homepage (https://mybrowseraddon.com/webapi-blocker.html).
Policy Control
Policy Control is an extension that helps you easily adjust all content settings (via contentSettings API) from the toolbar popup UI. These settings are adjusted on a website (domain) basis. Once you open the toolbar popup UI, the tab URL will appear at the top section in the UI as a pattern (i.e. http://example.com/*). Adjust what you need for this pattern and then reload the webpage. Please note, all changes are auto-saved to the memory. If you want to reset the content setting changes to the default values, please press the reset button at the top toolbar. Note: The extension interface supports dark mode. To switch the interface theme to dark, please press the moon icon in the top-right toolbar. To report bugs, please fill out the bug report form on the addon's homepage (https://mybrowseraddon.com/policy-control-wext.html).
