cryptographic_function
NPS-BFE803BB2387
This file implements HKDF (HMAC-based Key Derivation Function) using Node.js crypto's createHmac. It performs standard key derivation operations, hashing input key material with a salt and info parameter. No external communication, environment access, obfuscation, file system manipulation, process spawning, or dynamic imports are present. This is a legitimate cryptographic utility.

| File | Verdict | What the reviewer saw |
|---|---|---|
| dist/node/cjs/index.js | safe | Cleared by Jev triage; no further analysis needed |
| dist/node/cjs/runtime/fallback.js | safe | No malicious patterns detected; the code implements HKDF key derivation using Node.js crypto and performs no network, filesystem, process, or dynamic code execution. |
| dist/node/cjs/runtime/hkdf.js | safe | No malicious patterns detected; the file implements a standard HKDF key derivation wrapper with a fallback, using only Node.js crypto APIs and no external network, filesystem, or process operations. |
| dist/node/esm/index.js | safe | Cleared by Jev triage; no further analysis needed |
| dist/node/esm/runtime/fallback.js | safe | Legitimate HKDF key derivation implementation using crypto.createHmac with no malicious patterns detected. |
