Covers its OpenSSL foundation, the switch from hand-written JSI plumbing to the Nitro Modules codegen framework, the addition of WebCrypto subtle APIs, Ed25519/X25519, and OpenSSL 3.6's ML-KEM/ML-DSA/SLH-DSA post-quantum algorithms. Details a six-phase security audit (fixing a sliced-ArrayBuffer bug, an XSalsa20 keystream reuse vulnerability, missing DH/ECDH peer-key validation, and a Bleichenbacher padding oracle on RSA PKCS#1 v1.5), benchmark results showing up to 7,480x speedups over pure-JS alternatives, and download growth from ~47,000/week to ~244,000/week over a year. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What security vulnerabilities were found in react-native-quick-crypto's security audit? A six-phase security audit found several critical issues, including a sliced ArrayBuffer byte-offset bug in timingSafeEqual and AEAD setAAD that compared or authenticated the wrong bytes, an XSalsa20 keystream restart bug causing a catastrophic two-time-pad in streaming Cipheriv, missing DH/ECDH peer-key validation allowing off-curve or small-subgroup attacks, and a Bleichenbacher padding oracle on RSA PKCS#1 v1.5 decryption, fixed via OpenSSL 3.2+ implicit rejection. _daily.dev surfaces writeups like this for teams auditing crypto dependencies before shipping to production._ ### How much faster is react-native-quick-crypto than pure JavaScript crypto libraries like noble or crypto-browserify? Native OpenSSL-backed operations in react-native-quick-crypto are dramatically faster than pure-JS alternatives: DH modp14 key generation is about 7,480x faster than crypto-browserify, HMAC SHA-256 on an 8 MB buffer is 1,418x faster than @noble/hashes/hmac, and utf16le encoding of 1 MB strings is roughly 992x faster than the Buffer polyfill, largely because pure-JS BigInt math can't match OpenSSL's tuned assembly. _Developers comparing crypto approaches for React Native can track benchmark deep dives like this on daily.dev._ ### Does react-native-quick-crypto support post-quantum cryptography algorithms like ML-KEM and ML-DSA? Yes, react-native-quick-crypto added ML-KEM, ML-DSA, and SLH-DSA support after OpenSSL 3.6 introduced native implementations of these NIST post-quantum finalists. ML-KEM supports encapsulate/decapsulate and key wrapping with raw-public and raw-seed export/import, ML-DSA supports sign/verify with JWK and PKCS#8 import/export, and SLH-DSA supports sign and verify, all usable on iOS and Android through the standard subtle and KeyObject APIs. _Follow post-quantum crypto adoption in mobile libraries on daily.dev as teams plan migrations._ ## Similar posts
