Review rev_c19c6b0e4c624418a2f374e5a84aea15

{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/modes/polyval.c`, which is a small POLYVAL/GHASH transform implementation for 16-byte blocks. I checked for install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/include/openssl/rc4.h`, which is a plain RC4 API header defining `RC4_KEY` and the `RC4_set_key`/`RC4` function declarations. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.\n`aws-lc/ssl/span_test.cc` is a small GoogleTest unit test for the `Span` and `MakeSpan`/`MakeConstSpan` APIs, exercising constructors, accessors, and array/vector conversions. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed this README-only documentation file for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior. It only describes the aws-lc-fips-sys crate, its FIPS build/version notes, build prerequisites, support links, and security contact process; no concrete malicious or supply-chain indicators were present.\nReviewed `aws-lc/crypto/asn1/a_d2i_fp.c`, which contains two small ASN.1 deserialization helpers that read ASN.1 from a `BIO`/`FILE*`, pass the bytes to `ASN1_item_d2i`, and then free the temporary buffer. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain compromise indicators, and found none in this file.",
