Technical Details: Hardware-based Keystore Security
Kriptor uses a hardware-based keystore to securely store your private key. This ensures the private key is generated and maintained within a protected hardware environment, inaccessible to the operating system or applications. Your private key is never exported or loaded into device memory, making it completely secure from external threats.
Protection Against Attacks:
- Resistant to Cold Boot Attacks
- Resistant to Memory Attacks
- Resistant to Dump Attacks
- Resistant to Root Attacks
Potential Vulnerabilities (Very Rare Cases):
- Device compromised at hardware level
- TEE compromised
- Biometric authentication bypassed
- Physical device tampering
The hardware keystore leverages secure cryptographic modules, like the Trusted Execution Environment (TEE) or Secure Element, ensuring cryptographic operations occur within a safe and isolated environment. This method enables strict access controls, such as mandatory user authentication for cryptographic operations, significantly enhancing security.
Due to these robust security measures, Kriptor is perfect for governments, enterprise executives, journalists, and other security-sensitive users who require unbreakable messaging privacy.
