A pure JavaScript port of the TweetNaCl cryptography library, providing high-security, easy-to-use cryptographic primitives.
TweetNaCl.js is a JavaScript port of the TweetNaCl cryptographic library, providing essential primitives like public-key encryption, secret-key encryption, digital signatures, and hashing. It solves the need for a high-security, easy-to-integrate cryptography library that works consistently across browsers and Node.js environments.
JavaScript developers building applications that require secure communication, data encryption, digital signatures, or cryptographic key exchange, particularly those who need a reliable, audited library without native dependencies.
Developers choose TweetNaCl.js for its strong security guarantees, having passed a professional audit, its pure JavaScript implementation that works everywhere, and its straightforward API that mirrors the trusted TweetNaCl/NaCl ecosystem.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Professionally audited by Cure53 with no security issues found, providing high confidence in its implementation, as stated in the audit report linked in the README.
Offers a full suite of essential cryptographic functions including public-key encryption, signatures, hashing, and random bytes generation, all in one library, as detailed in the Key Features section.
No native dependencies, ensuring consistent operation across modern browsers and Node.js without installation hassles, highlighted in the System Requirements.
Implements algorithmic constant-time comparisons to help mitigate timing attacks, a key security feature mentioned in the README's Security Considerations.
Being a JavaScript port, it's slower than native implementations; benchmarks show nacl-fast.js improves speed but still lags behind C-based alternatives, as evidenced in the performance table.
The README explicitly warns about limitations like no secret key commitment, signature malleability, and hash length-extension attacks, requiring careful protocol design to avoid vulnerabilities.
All API functions use Uint8Arrays, so developers must handle string encoding/decoding separately with external utilities, adding complexity to basic operations.
