{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/modes/ctr.c`, which implements AES CTR-mode counter increment and block processing helpers. I found no concrete indicators of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/crypto/x509/x509_obj.c`, which implements `X509_NAME_oneline` by formatting X.509 name entries into a slash-delimited string with length checks and hex-escaping for non-printable bytes. I found no concrete malicious or supply-chain indicators in this file: no install-time hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed this AVX2 assembly source for `mlkem_tomont_avx2`, which performs in-place Montgomery-domain conversion on polynomial buffers using fixed constants and vector multiply/subtract instructions. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators.\nReviewed `aws-lc/ssl/CMakeLists.txt`, which defines the `ssl` library build, test executables, and install/export rules. I checked for install-time hooks, hidden subprocess or network activity, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed this Windows-specific jitterentropy support header, which provides inline helpers for timing reads, zeroing/freeing memory, FIPS checks, and CPU/yield stubs. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in the target file.",
