{
  "summary": "Reviewed `aws-lc/include/openssl/hpke.h`, which is a C/C++ header declaring HPKE constants, types, and API entry points plus stack-allocation helpers; it contains no executable implementation logic. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/third_party/s2n-bignum/s2n-bignum-imported/x86_att/p521/bignum_mul_p521.S`, an x86-64 assembly routine that performs modular multiplication for P-521 and writes the reduced result back to the output buffer. I checked the file for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators.\nReviewed `aws-lc/crypto/cipher_extra/e_aes_cbc_hmac_sha256.c`, which implements AES-CBC with HMAC-SHA256 stitching for TLS encryption/decryption and constant-time record handling. I checked for install-time hooks, network/exfiltration, credential or secret access, dynamic code loading, obfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators in this file.",
