Secure. Simple. Powerful.
SSP Key is your two-factor authentication (2FA) solution for the SSP Wallet. It securely holds the secondary private key required to construct 2-of-2 multisignature addresses and sign transactions. With its own independent seed phrase, SSP Key operates on true blockchain protocol standards, providing fully enforced multisignature, multi-asset accounts.
This powerful tool brings the simplicity and security of multisignature technology to average users, making it easier than ever to manage multisignature addresses across multiple assets. SSP Key empowers users with the highest level of protection while maintaining a user-friendly interface, ensuring anyone can benefit from robust, blockchain-based security without complexity.
SSP Key is an essential part of the SSP Wallet ecosystem, enabling a 2-of-2 multisignature system for unmatched security:
- SSP Wallet manages one private key.
- SSP Key (on your mobile device) holds the second private key.
Both keys are required to authorize transactions, ensuring that your funds remain secure even if one device is compromised.
- Secure Storage: User passwords, tokens and sensitive data are stored with
react-native-keychainand further in MMKV with AES encryption provided by CryptoJS. - Unique Device Encryption: Encryption is done by combining random string generated by
crypto.getRandomValues(new Uint8Array(64))with user input (password or PIN), ensuring device-specific encryption. - Randomized Security: Salts and initialization vectors (IVs) are randomly generated to enhance encryption robustness.
- Performance Focused: Avoids underperforming libraries like Cryptr, ensuring optimal functionality in React Native environments.
