Detect cryptographic algorithms used in JavaScript source code. Identifies AES/RSA/SM2/SM3/SM4/HMAC/MD5/SHA family algorithms with evidence, key/IV source tracking, and cipher mode. Input: JS source code string. Returns list of detected crypto usages with algorithm type, location (line/col), evidence snippet, key source, IV source, and mode (CBC/ECB/GCM/CTR etc).

Identify the obfuscation/packing technique used in JavaScript code. Detects webpack bundles, AAEncode, JJEncode, JSFuck, obfuscator.io, JavaScript obfuscator, babel minified, packer (Dean Edwards), UPX-style, eval-based loaders, and control-flow flattening. Input: JS source code. Returns obfuscation type, confidence, unpack hints, and recommended deobfuscation strategy.

Reconstruct a standalone implementation of a cryptographic algorithm from JS source + captured input/output samples. Given the original JS code and (optionally) sample input→output pairs, generate a self-contained Python implementation that reproduces the same transformation. Supports common AES/RSA/HMAC/MD5/SHA/SM2/SM3/SM4 patterns. Input: source code, optional samples (array of {input, output} pairs), target language (python/node). Returns reconstructed code + verification notes.

Generate a ready-to-use SDK (Python/Node/Go) from a reversed API contract. Given endpoint URL, HTTP method, headers, body template, and the signature/encryption algorithm spec, produce a complete SDK file with: request construction, crypto signing, error handling, and usage example. Input: API spec (url, method, sign algorithm description, params). Returns SDK code in requested language.

Generate anti-debugging bypass scripts for common anti-debug techniques. Detects and generates bypass for: debugger statement loops, setInterval debugger, devtools detection (window size, console access, Function.toString), timing checks, console.log getter traps, and CodeMirror/eruda detection. Input: JS source code or technique name. Returns bypass injection script + injection instructions.

Extract cryptographic constants from JS source code. Identifies S-boxes (AES/DES), initial hash values (SHA-256/SHA-1/MD5/SM3), round constants, elliptic curve parameters (SM2/NIST curves), magic numbers, and known crypto constant arrays. Input: JS source code. Returns list of found constants with their crypto algorithm association and location.
