🔌 API Endpoints

POST /api/search

Search for hashes or generate from plaintext

Input: { query: string }
Output: Hash results or generated hashes

GET /api/health

Check system health and Elasticsearch status

Output: System status and statistics

📦 Installation & Setup

Quick Start

# Install dependencies
npm install

# Start development server
npm run dev

# Build for production
npm run build

# Start production server
npm start

Bulk Indexing

# Index a wordlist file
npm run index-file wordlist.txt

# With custom batch size
npm run index-file wordlist.txt -- --batch-size 500

Environment Configuration

# Optional: Set Elasticsearch endpoint
export ELASTICSEARCH_NODE=http://localhost:9200

🗄️ Elasticsearch Configuration

Index: `hasher`

Shards: 10 (horizontal scaling)
Replicas: 1 (redundancy)
Analyzer: Custom lowercase analyzer

Schema

{
  "plaintext": "text + keyword",
  "md5": "keyword",
  "sha1": "keyword",
  "sha256": "keyword",
  "sha512": "keyword",
  "created_at": "date"
}

🎯 Supported Hash Algorithms

Algorithm	Length	Pattern
MD5	32	`^[a-f0-9]{32}$`
SHA1	40	`^[a-f0-9]{40}$`
