Review rev_dc85d25695384802b53b87f31ab7c400

{
  "summary": "Reviewed `src/client/builder.rs`, which implements the client configuration builder for rustls, including ECH selection, root-certificate verifier setup, and client-auth certificate wiring. I found no concrete indicators of install hooks, network/exfiltration, credential harvesting, dynamic code loading, obfuscation, or persistence; the only risky surface is an explicitly named dangerous custom certificate verifier API, which is a documented trust boundary rather than hidden behavior.\nReviewed `src/crypto/signer.rs`, which defines signing-key traits, certificate/key pairing helpers, and SPKI serialization for TLS authentication. I checked for install-time execution, network or exfiltration behavior, credential harvesting, hidden dynamic loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\n`src/x509.rs` is a small DER/ASN.1 helper module that wraps byte slices into SEQUENCE, BIT STRING, and OCTET STRING encodings, with unit tests for length encoding. I checked it for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.\nReviewed `src/builder.rs`, which is a Rustls configuration-builder module for constructing client/server TLS configs and validating protocol versions and cipher-suite/key-exchange compatibility. I checked for install hooks, subprocess execution, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/manual/howto.rs`, which is a documentation-only file describing rustls custom signing-key integration and debugging guidance, including `tcpdump` captures and `SSLKEYLOGFILE` for test-time decryption. I found no concrete malicious or supply-chain indicators in the target file: no install hooks, hidden subprocess execution, network exfiltration, credential harvesting, dynamic code loading, obfuscation, or persistence behavior beyond explicitly signposted debugging advice.",
