Review rev_c8770849a1d844738c46df5da549aa25

{
  "summary": "Reviewed `aws-lc/crypto/x509/x509_txt.c`, which is a straightforward certificate verification error-string mapping function. 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.\nReviewed `aws-lc/crypto/pkcs7/pkcs7_asn1.c`, which defines PKCS7 ASN.1 encode/decode structures and a BER-to-DER normalization path in `d2i_PKCS7`. I found no concrete indicators of malicious or supply-chain behavior: there are no install hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation, or persistence logic in this file.\nReviewed `aws-lc/ssl/test/runner/shim_dispatcher.go`, which implements a local TCP shim dispatcher for test runners: it binds to loopback, assigns shim IDs, accepts connections, and routes them to in-memory listeners. I checked for install hooks, hidden subprocess execution, network exfiltration, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators.\nThis file is a small C implementation of the socket BIO layer for aws-lc, wrapping normal OS socket read/write/close operations and BIO control handling. I checked for hidden subprocess execution, credential access, exfiltration beyond ordinary socket I/O, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.\nReviewed aws-lc/crypto/x509/x509_trs.c, which implements X.509 trust lookup and compatibility checks for standard trust IDs and certificate auxiliary trust/reject lists. I checked for install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
