{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/ec/p256_table.h`, which is a generated C header containing static P-256 precomputed point tables guarded by `BORINGSSL_NISTP256_64BIT`. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, subprocesses, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/third_party/s2n-bignum/x86_att/p521/bignum_sqr_p521.S`, which is a hand-written x86-64 assembly routine for squaring a 521-bit field element modulo p_521. I checked it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other payload execution patterns; none were present.\nReviewed `aws-lc/crypto/digest_extra/digest_extra.c`, which implements digest NID/OID/name lookup plus small EVP wrappers for BLAKE2b256 and a null digest. 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 Perl perlasm generator for ARMv8 GHASH/GMULT assembly. It only emits local assembly text and a small constant table, and I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence.",
