Could you build this?
No Writing a pure-Rust cryptographic library that outperforms established implementations requires specialized expertise in constant-time algorithms, assembly optimizations (SIMD/AVX-512), and rigorous cryptanalysis to prevent side-channel leaks.
What it would actually take: Building competitive cryptography requires deep mathematical and security domain knowledge, implementing primitives (AES, ChaCha20, SHA, Curve25519) with hand-crafted SIMD vector assembly. The codebase must undergo formal verification, side-channel analysis (timing attacks, power analysis), and extensive fuzzing against standard test vectors. A solo vibe coder cannot ensure both cryptographic security and top-tier hardware-level performance.
Discussion
15 comments analyzed.
Competitors mentioned: aws-lc-rs, ring, RustCrypto, blake3 crate, OpenSSL
Concerns raised: Lacks third-party audit before production use, Incomplete constant-time implementation across all primitives, LLM-generated code and documentation quality concerns, Code duplication in SHA variants creates maintenance/audit burden, Potential performance gains from missing constant-time properties
Feature requests: Constant-time matrix documentation replacing compressed line, Reduce wrapper/finalization code duplication in SHA implementations, Expand Wycheproof test vector coverage beyond RSA
