Review rev_3551385a59d04b77aedc3cdb62ddea3f

{
  "summary": "Reviewed `aws-lc/crypto/dsa/internal.h`, which only declares the internal `DSA` struct layout and a key-check helper. I found no concrete supply-chain indicators in this file: no install hooks, subprocess execution, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/kyber/pqcrystals_kyber_ref_common/symmetric-shake.c`, which only defines two small Kyber SHAKE helper functions that append a byte or nonce to an input buffer and pass the result into local SHAKE primitives. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/include/openssl/posix_time.h`, which is a small public C header declaring POSIX time conversion APIs (`OPENSSL_posix_to_tm`, `OPENSSL_tm_to_posix`, `OPENSSL_timegm`). I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found none in this target file.\nReviewed `aws-lc/ssl/test/fuzzer_tags.h`, a small header that defines numeric tags used by the TLS fuzzer harness to label session, client-cert, handoff, handback, and hint data. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found none in this file.\n`aws-lc/crypto/des/des_test.cc` is a small GoogleTest unit test that checks DES weak-key detection and key parity handling via local library calls. I reviewed it for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.",
