A fast, pure-JavaScript implementation of elliptic curve cryptography supporting ECDSA signing/verification, ECDH key exchange, and EdDSA. It runs in Node.js and browsers without native dependencies.

Use cases

• sign and verify messages with ECDSA in JavaScript
• generate elliptic curve key pairs in the browser
• perform ECDH key agreement in Node.js
• implement blockchain transaction signing with secp256k1
• add ECC to a JavaScript app without native modules

When to choose

• you need elliptic curve crypto in pure JavaScript with no native dependencies
• you need secp256k1 or other common curves in Node or the browser
• you need Ed25519/EdDSA support in JavaScript

When to avoid

• you can use the built-in Node.js crypto module or WebCrypto for better performance and security
• you need audited, side-channel-resistant cryptography for high-security production use
• you need RSA or symmetric encryption
