{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/md5/md5.c`, which is a conventional MD5 digest implementation and block compressor with state init/final/update helpers. I checked for install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation/packing, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the ARM assembly implementation of `bignum_mul_6_12_alt`, which is a straight-line 6x6 limb multiplication routine that loads operands, performs arithmetic, stores the 12-limb result, and returns. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `aws-lc/ssl/bio_ssl.cc`, which is a C++ implementation of the SSL BIO wrapper around `SSL_read`, `SSL_write`, and related control paths. I found no concrete indicators of install hooks, network exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed aws-lc/crypto/fipsmodule/bn/random.c, which implements BIGNUM random and range-generation helpers using RAND_bytes/RAND_bytes_with_user_prediction_resistance plus FIPS service-indicator locking. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.",
