Generate secure random secret keys for JWT, API keys, session keys, and more. Supports various formats and lengths.
Characters: 32
💡 Tips:
- • For JWT secrets, use at least 32 characters with alphanumeric type

Secret Key Generator Information
What is a Secret Key?
A secret key is a crucial security element used for JWT token signing, API authentication, session management, encryption, and more. It must be sufficiently complex and random, making it difficult to predict. This tool generates secure secret keys in various formats and lengths.
How Does It Work?
Select your desired key length and format, then click 'Generate Secret Key' to create a cryptographically secure random key. This feature runs entirely in your browser, ensuring no information is sent to any server for maximum security.
Use Cases
JWT signing keys, API authentication tokens, session encryption keys, database encryption keys, cookie signing keys, OAuth secrets, webhook verification keys, and more. Suitable for use from development environments to production systems.
Security Notice
Store generated secret keys securely and never expose them publicly. Avoid hardcoding them in your codebase; use environment variables or secure vaults instead. Regular key rotation is recommended. This tool operates locally in your browser and does not send any information to servers.
