ECDSA Curve Calculator
ECDSA & Elliptic Curves
What is ECDSA?
Elliptic Curve Digital Signature Algorithm (ECDSA) is used to create digital signatures in cryptocurrencies. It provides strong security with smaller key sizes compared to RSA.
How It Works:
- Generate a random 256-bit private key
- Multiply by curve's generator point → public key
- Sign message: hash(message) + private key → signature (r, s)
- Verify: use public key to verify signature is valid
Curve Comparison:
| Curve | Speed | Security | Notes |
|---|---|---|---|
| secp256k1 | Fast | Very Strong | Standard for Bitcoin/Ethereum |
| secp256r1 | Fast | Very Strong | NIST standard, government use |
| Ed25519 | Fastest | Very Strong | Modern, performance-focused |
Why Elliptic Curves?
- Smaller keys: 256-bit ECC ≈ 3072-bit RSA security
- Faster: Quicker signature generation/verification
- Less bandwidth: Smaller signatures and keys
- Battery friendly: Important for mobile devices
🔐 Security Considerations:
- Private key must be truly random (use cryptographically secure RNG)
- Never reuse nonce (k) value - leads to private key recovery!
- Deterministic signatures (RFC 6979) prevent nonce reuse
- 256-bit curves provide ~128-bit security level
- Quantum computers may break ECDSA in the future
