Review rev_cc92469cad1a4e6c91e7aa061b0ed59a

{
  "summary": "Reviewed `aws-lc/crypto/thread.c`, which is a small C shim that stubs legacy OpenSSL thread-callback APIs and returns fixed values or no-ops. I checked for install-time execution, network or exfiltration paths, credential/secret access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/x509/x509rset.c`, which only contains X509 request setter helpers for version, subject name, public key, signature algorithm, and signature value. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators.\nReviewed `aws-lc/include/openssl/md5.h`, a public MD5 API header that only defines constants, a state struct, and exported function prototypes for hashing. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nI reviewed `aws-lc/crypto/decrepit/evp/evp_do_all.c`, which is a small OpenSSL compatibility shim that enumerates fixed cipher and digest names by calling built-in `EVP_*` constructors and a caller-supplied callback. 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, persistence, or hidden subprocess execution.\nReviewed `aws-lc/crypto/x509/x509_d2.c`, which only defines `X509_STORE_set_default_paths` and `X509_STORE_load_locations` for loading certificate trust stores from file and directory inputs, then clearing the error queue. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
