📘 What is an EC Key used for?
- SSL/TLS Certificates: Used in HTTPS to secure websites with smaller, faster keys compared to RSA.
- Digital Signatures: EC keys are used to sign JWT tokens, code, and documents using ECDSA.
- SSH Authentication: Common in modern SSH setups (e.g.,
ecdsa,ed25519) for logging into servers. - Mobile & IoT Devices: Ideal for devices with limited CPU/battery due to efficiency.
- Blockchain & Crypto: Cryptocurrencies like Bitcoin and Ethereum use EC keys (e.g.,
secp256k1). - Zero-Knowledge Systems: Power advanced cryptography like zk-SNARKs and private coins (e.g., Monero).
⚙️ EC vs RSA Comparison:
| Feature | EC (Elliptic Curve) | RSA |
|---|---|---|
| Key Size | Smaller (256-bit) | Larger (2048+ bit) |
| Performance | Faster | Slower |
| Security per Bit | Higher | Lower |
| Mobile Friendly | ✅ Yes | ❌ Less ideal |
| Bandwidth Usage | Lower | Higher |
⚠️ Important: Keep your private key secure and never share it. This tool generates keys locally in your browser. Always store private keys in a secure location.
