Review rev_bf5249b5dea249109070045b95609b31

{
  "summary": "Reviewed the `aws-lc/include/openssl/md4.h` header, which only declares MD4 constants, context structure, and exported digest/transform APIs for the crypto library. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed `aws-lc/include/openssl/pool.h`, which is a C/C++ header that only declares `CRYPTO_BUFFER_POOL` and `CRYPTO_BUFFER` APIs and related inline deleter helpers; it contains no executable implementation. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain indicators and found none in this file.\nReviewed `aws-lc/crypto/fipsmodule/evp/p_ed25519.c`, which implements Ed25519 EVP key generation, signing, and verification wrappers. I checked for install hooks, hidden subprocesses, 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/test/file_test_gtest.cc`, which is a small GoogleTest helper that reads test data into a `FileTest` wrapper and reports test failures/error-queue state. I found no concrete supply-chain or malicious indicators in this file: no install hooks, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation, persistence, or other hidden subprocess execution.\nReviewed this x86-64 assembly routine for optional negation modulo P-521. It is a small arithmetic function with ABI shims and constant-time bitwise operations; I found no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence mechanisms in the target file.",
