{
  "summary": "Reviewed `aws-lc/crypto/x509/x_x509a.c`, which only implements X509 auxiliary ASN.1 helpers for alias/keyid/trust/reject metadata and simple setters/getters/clearers. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this target file.\nReviewed `aws-lc/util/fipstools/acvp/acvptool/subprocess/hash.go`, which is a straightforward ACVP hash test-vector processor that decodes JSON inputs, validates message lengths, and forwards byte slices to a subprocess via `Transactable` for hashing. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this file.\nReviewed `aws-lc/crypto/pkcs7/internal.h`, which is a PKCS#7 internal C header defining ASN.1-backed structs and two helper APIs for parsing and emitting SignedData. I checked for install-time hooks, network or credential access, hidden code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior in this file.\nReviewed `aws-lc/include/openssl/aes.h`, which is a public AES API header containing constants, the `AES_KEY` struct, and function declarations for block cipher and key-wrap operations. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed `aws-lc/crypto/x509/x509_obj.c`, which implements `X509_NAME_oneline` for formatting X.509 subject/issuer names into a bounded printable string. I checked for install hooks, network or credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths; none were present in this file.",
