Review rev_7c0e9e7ec3a54e1dab6301032fbd2d84

{
  "summary": "Reviewed `src/ec/curve25519/x25519.rs`, which implements X25519 key agreement, private-key generation from an RNG, public-key derivation, and ECDH with all-zero shared-secret rejection per RFC 7748. 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/deobfuscation, or persistence/tampering logic.\nReviewed `src/ec/suite_b.rs`, which implements elliptic-curve point validation for P-256/P-384 and PKCS#8 private-key parsing/consistency checks. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration paths, credential/env access, dynamic code loading, obfuscation/decoding pipelines, or persistence/tampering behavior.\nReviewed `src/agreement.rs`, which implements ephemeral key agreement for X25519 and NIST P-256/P-384 plus public-key wrappers and the `agree_ephemeral` flow. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed `tests/ed25519_tests.rs`, which is a pure Ed25519 test module that exercises signing, verification, PKCS#8 parsing, and embedded test vectors via `include_bytes!`/`test::run`. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed the ChaCha20-Poly1305 integrated Rust wrapper in `src/aead/chacha20_poly1305/integrated.rs`, including the CPU-feature dispatch and both `seal`/`open` FFI paths. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration calls, secret/credential access, dynamic code loading, obfuscation/deobfuscation, or persistence behavior; it is a thin cryptographic wrapper over local assembly symbols.",
