Review rev_6ba03e77c06e40fcbc954c8a45010447

{
  "summary": "Reviewed `src/arithmetic/ffi.rs`, which is a small Rust FFI adapter around Montgomery multiplication with length checks and pointer-passing into an external C/assembly routine. I found no concrete malicious or supply-chain indicators in this file: no install hooks, no network or exfiltration, no credential access, no dynamic code loading, no obfuscation, and no persistence behavior.\nReviewed `src/rsa/public_modulus.rs`, which implements RSA public modulus parsing, size validation, byte iteration, and cached Montgomery setup. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/ec/suite_b/ecdsa/digest_scalar.rs`, which contains deterministic ECDSA digest-to-scalar conversion logic plus unit tests. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this file.\nReviewed `src/io/positive.rs`, which is a small serializer/deserializer helper for positive big-endian integers backed by `untrusted::Input`. I checked for install hooks, network or exfiltration paths, credential or environment access, dynamic code loading, obfuscation, persistence, and other hidden execution behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/polyfill/slice/as_chunks_mut.rs`, which is a small Rust slice polyfill/helper that splits a mutable slice into fixed-size chunk views and iterators. I checked it for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators.",
