{
  "summary": "Reviewed `crypto/fipsmodule/ec/p256-nistz.h`, which is a C header declaring P-256 finite-field and point-operation APIs behind `OPENSSL_USE_NISTZ256` and x86_64 feature gates. I checked it for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/rsa/padding/pkcs1.rs`, which contains standard PKCS#1 v1.5 RSA signature padding/verification logic and static DigestInfo prefixes for SHA-1/256/384/512. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.\nReviewed `crypto/limbs/limbs.c`, which is a low-level big-number limb arithmetic implementation for constant-time comparisons, modular add/subtract, shifts, and multiply-add helpers. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation/packing, or persistence behaviors.\nReviewed `src/aead/poly1305_test.txt`, which appears to be a static Poly1305 test-vector corpus copied from OpenSSL/RFC sources. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/aead/quic.rs`, which implements QUIC header-protection key setup and mask generation for AES-128, AES-256, and ChaCha20. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators; none were present in this file.",
