{
  "summary": "Reviewed `aws-lc/ssl/test/runner/shim_ticket.go`, which implements local AES-CBC/HMAC helpers and DER parsing for encrypting, decrypting, and editing TLS shim tickets in test code. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence tampering.\nReviewed `aws-lc/crypto/asn1/a_utf8.c`, which only implements UTF-8 encode/decode helpers (`UTF8_getc` and `UTF8_putc`) with length and minimal-encoding checks. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this target file.\nReviewed `aws-lc/crypto/dilithium/p_dilithium3_asn1.c`, which implements Dilithium3 EVP_PKEY ASN.1 encode/decode, raw key setters/getters, comparison, and size/bit-length helpers. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed this Go test-vector generator for secp256k1 ECDSA. It only produces deterministic sign/verify fixtures from local computation and printed output; I found no install hooks, network or exfiltration paths, secret access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise indicators in this file.",
