{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/ec/builtin_curves.h`, which is a generated header of static elliptic-curve parameter tables for P-224, P-256, P-384, P-521, and secp256k1 across 32-bit and 64-bit builds. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `aws-lc/crypto/fipsmodule/sha/asm/sha1-armv8.pl`, a Perl perlasm generator that emits ARMv8 SHA-1 assembly and pipes it through `arm-xlate.pl` during code generation. I found no concrete malicious or supply-chain indicators in the target file: no install hooks, network/exfiltration, credential access, hidden downloads, obfuscation, or persistence behavior were present.\nReviewed `aws-lc/crypto/fipsmodule/kdf/sskdf.c`, which implements the SSKDF digest and HMAC key-derivation paths with explicit FIPS service-indicator handling and bounded buffer copying. 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 in this file.",
