{
  "summary": "Reviewed the Perl perlasm generator in `aws-lc/crypto/fipsmodule/bn/asm/bn-armv8.pl`, which emits AArch64 big-number add/subtract assembly and forwards it to `arm-xlate.pl` through a local pipe. 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/crypto/fipsmodule/cpucap/cpu_aarch64_linux.c`, which is a Linux AArch64 CPU-capability probe that reads hardware features via `getauxval`, optionally probes `MIDR_EL1`, and allows an `OPENSSL_armcap` environment override. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed this target header, which only declares ECDH APIs and related error constants. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in the file.\nReviewed `aws-lc/util/ar/ar_test.go`, which is a Go unit test that opens bundled archive fixtures, parses them with `ParseAR`, and compares extracted entries against expected bytes. I checked for install hooks, subprocess execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/fipsmodule/digest/internal.h`, which only declares internal digest and EVP_MD_CTX function-pointer structs and contains no executable logic. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
