CryptKeeper

Extension that stores credentials and creates semaphore proofs

Features & Capabilities

Meet CryptKeeper, an avant-garde browser extension revolutionizing the realm of online privacy and anonymity. It leverages the power of Zero-Knowledge Identity Management and Proof Generation to ensure your online interactions remain anonymous yet credible.

Engineered with advanced protocols such as Semaphore and RLN, CryptKeeper is designed to ensure absolute privacy - no personal information is ever stored or transmitted. Its unique capability lies in employing Zero-Knowledge Proofs, a cryptographic technique which allows you to authenticate yourself within a group of authorized users without revealing your individual identity.

Experience a seamless blend of privacy and usability with CryptKeeper - navigate the web confidently without compromising on your identity.

Key Features:

  • Anonymous Sign-In via Semaphore: CryptKeeper supports secure, anonymous sign-ins using Semaphore, a cutting-edge technology designed for privacy-focused applications. You can gain a deeper understanding of Semaphore at Semaphore's website.(https://semaphore.appliedzkp.org/)

  • Deterministic Anonymous Identities: With CryptKeeper, users can generate deterministic anonymous identities using a simple seed phrase. This feature provides an additional layer of privacy by ensuring each user's identity remains concealed and consistent.

  • Integration with Zkitter: CryptKeeper seamlessly integrates with Zkitter, an anonymous social network, enabling users to craft private identities. Users can generate and showcase a proof of reputation from their social media profiles, ensuring credibility without compromising privacy. (https://www.zkitter.com/)

Is CryptKeeper Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

CryptKeeper requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

CryptKeeper has earned a fairly good reputation and likely can be trusted.
