Karasoy eID 作者： Karasoy Teknoloji A.Ş.

Karasoy eID lets you sign in to supported Turkish web applications using your qualified electronic signature (e-imza).

Features:
- Smart card and USB token support
- Compatible with TÜRKTRUST, E-Tuğra, e-Güven, TÜBİTAK KamuSM certificates
- Native Messaging — signing happens entirely on your local machine; the private key never leaves your device
- No user data is collected, no ads, no analytics

How to use:
1. Install this Karasoy eID browser extension
2. Download and install the Karasoy eID desktop application from https://karasoy.com.tr (required for smart card/USB token communication)
3. On a supported site (e.g. callturk.com.tr) click "E-imza ile Giriş"
4. Pick your certificate, enter your PIN — signed authentication data is sent over a secure channel

Supported sites: callturk.com.tr (CallTurk admin panel)

Privacy: Karasoy eID does NOT collect user data, does not run analytics, and does not share data with third parties. The extension only activates on supported sites and only talks to the native host when you request a signature.
