Secure Key Generator

Generate cryptographically secure keys for Django, APIs, JWT, Redis, and more!

Django SECRET_KEY for settings.py

General purpose API authentication key

JSON Web Token signing secret

Redis authentication password

Safe database password (no special chars)

Universally unique identifier

Customizable key with your preferences

Advanced Options

Security Level: Excellent
323 bits of entropy
SECRET_KEY = "your-generated-key-here"

Cryptographically Secure

All keys are generated using crypto.getRandomValues() for maximum security.

Entropy Guidelines

  • • 128+ bits: Excellent (recommended)
  • • 80-127 bits: Good for most uses
  • • 60-79 bits: Fair for low-risk
  • • <60 bits: Weak (not recommended)

Best Practices

  • • Store keys securely (env files)
  • • Never commit keys to version control
  • • Rotate keys regularly
  • • Use different keys per environment

Key Types & Presets

Framework Keys

  • • Django Secret Key: 50-char mixed for SECRET_KEY
  • • JWT Secret: 64-char base64 for token signing
  • • API Key: 32-char base64 for authentication
  • • UUID v4: Standard unique identifiers

Database & Infrastructure

  • • Redis Password: 24-char alphanumeric
  • • Database Password: 20-char safe characters
  • • Custom Keys: Fully customizable options
  • • Batch Generation: Up to 20 keys at once

Output Formats

Base64

URL-safe Base64 encoding (like openssl rand -base64)

kJ8vN2mQ7xR9...

Hexadecimal

Lowercase hex characters (0-9, a-f)

a1b2c3d4e5f6...

Alphanumeric

Letters and numbers only (safe for databases)

K8vN2mQ7xR9...

Security Features

Cryptographic Security

  • • Uses crypto.getRandomValues() (CSPRNG)
  • • Entropy calculation and security rating
  • • No predictable patterns or sequences
  • • Suitable for production environments

Customization Options

  • • Exclude ambiguous characters (0, O, 1, l, I)
  • • Custom length (8-128 characters)
  • • Prefix and suffix support
  • • Multiple output formats

Common Use Cases

Django Development

Generate a secure SECRET_KEY for your Django settings.py:

SECRET_KEY = "your-generated-50-character-key-here"

API Authentication

Create secure API keys for service authentication:

X-API-Key: your-generated-api-key-here

Environment Variables

Secure keys for .env files and configuration:

JWT_SECRET=your-jwt-secret-here
REDIS_PASSWORD=your-redis-password-here
DB_PASSWORD=your-database-password-here

💡 Pro Tip

This tool replicates the functionality of openssl rand -base64 32and similar commands, but with additional presets and customization options for different frameworks and use cases.

🔒 Security Best Practices

  • • Store keys in environment variables, never in code
  • • Use different keys for development, staging, and production
  • • Rotate keys regularly (every 90 days recommended)
  • • Never commit keys to version control systems
  • • Use key management services for production environments

Frequently Asked Questions

Are these keys cryptographically secure?

Yes. Keys are generated with your browser's crypto.getRandomValues(), a cryptographically secure random source (CSPRNG). It is the same class of randomness used by tools like openssl rand, suitable for production secrets.

Is it safe to generate production secrets in my browser?

Yes. Everything runs locally in your browser. The keys are never sent to a server, logged, or stored anywhere, so they exist only on your machine until you copy them.

What key types and presets are available?

You get ready-made presets for Django SECRET_KEY, JWT secrets, API keys, UUID v4, Redis and database passwords, plus fully custom keys in Base64, hexadecimal, or alphanumeric output.

Can I generate a Django SECRET_KEY with this?

Yes. The Django preset produces a 50-character mixed-character key you can paste directly into SECRET_KEY in your settings. Keep it in an environment variable rather than committing it to your repository.

Can I create several keys at once?

Yes. Batch generation lets you create up to 20 keys in a single run, which is handy when you need distinct secrets for development, staging, and production environments.
