常见问题
What key size should I use?+
2048-bit keys are currently considered secure and are faster for signing/verification. 4096-bit keys provide a larger security margin and are recommended for long-term keys, certificates, or high-security applications.
Are the generated keys secure?+
Keys are generated in your browser using the Web Crypto API with cryptographically secure random number generation. They are never transmitted to any server. Treat your private key like a password - never share it.
