{
  "summary": "Cargo.toml is a standard Rust crate manifest for `aws-lc-sys` 0.41.0, defining the package metadata, a build script (`builder/main.rs`), feature flags, and build-time dependencies. I checked this target for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence signals, and found no concrete malicious or supply-chain indicators in the manifest itself.\nReviewed the target file, a hand-written x86-64 assembly implementation of `bignum_cmul_p25519` for Curve25519 modular multiplication. It contains only register shuffling and arithmetic reduction logic; I found no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence logic in this file.\nReviewed this x86-64 assembly routine implementing modular subtraction for P-384 and checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence. It is a straight-line arithmetic implementation with ABI shims and no concrete malicious or supply-chain indicators.\nReviewed this AArch64 assembly routine for polynomial-to-byte conversion and found no concrete supply-chain or malicious indicators. The file is a short, auto-derived implementation with ABI metadata and stack-neutral arithmetic only; I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence tampering, and hidden subprocess execution, and none were present.\nReviewed `aws-lc/crypto/ocsp/ocsp_asn.c`, which defines OCSP ASN.1 structures and thin BIO wrappers for OCSP request/response serialization. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.",
