FAQ
What is ECC encryption?
ECC (Elliptic Curve Cryptography) is a public-key encryption technology based on elliptic curve mathematics. Compared to RSA, ECC uses shorter keys and offers higher computational efficiency at equivalent security levels.
What's the difference between ECC and RSA?
Both are asymmetric encryption algorithms. Key differences: ECC 256-bit ≈ RSA 3072-bit security; ECC is faster with shorter keys, ideal for mobile devices; RSA has broader adoption and better compatibility.
What's the difference between P-256, P-384, and P-521?
These are NIST standard elliptic curves: P-256 provides 128-bit security, suitable for most cases; P-384 provides 192-bit security for high-security needs; P-521 provides 256-bit security for extreme security requirements.
What is ECDSA signing?
ECDSA (Elliptic Curve Digital Signature Algorithm) is a digital signature algorithm based on elliptic curves. It can sign data with a private key and verify signatures with a public key, ensuring data integrity and authenticity. Widely used in SSL certificates and cryptocurrencies.
