Review rev_358d3edfc32941d19cc4c6957bb87b61

{
  "summary": "Reviewed `aws-lc/crypto/decrepit/cfb/cfb_test.cc`, which is a C++ unit test that exercises AES CFB1/CFB8/CFB128 encryption and decryption against fixed NIST test vectors. I checked for install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators; none were present in this file.\nReviewed `aws-lc/ssl/bio_ssl.cc`, which implements the SSL BIO adapter for reading, writing, control dispatch, shutdown, and callback forwarding around an `SSL*`. I found no concrete indicators of malicious or supply-chain behavior in this file: no install hooks, network/exfiltration logic, credential or secret access, dynamic code loading, obfuscation, or persistence tampering.\nReviewed `aws-lc/crypto/des/internal.h`, which only defines DES byte-pack/unpack macros and typed DES function declarations. I found no concrete malicious or supply-chain indicators in the target file, and none of the checked categories were present: install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence.\nReviewed `aws-lc/crypto/kyber/kem_kyber.c`, which is a thin wrapper around Kyber reference KEM implementations and static legacy KEM descriptors. I checked for install hooks, subprocess launches, network or exfiltration code, credential access, dynamic code loading, obfuscation, and persistence mechanisms; none were present in this file.\nReviewed `aws-lc/ssl/test/async_bio.cc`, a small test BIO wrapper that gates reads and writes with quotas and forwards control to an underlying BIO. I found no concrete supply-chain indicators: there are no install hooks, network or exfiltration paths, hidden downloads, dynamic code loading, obfuscation, persistence, or secret-access behavior in this file.",
