Algorithm Configuration

Key Information

Algorithm
HS256
Key Length
256 bits (32 bytes)
HMAC with SHA-256 - Recommended minimum: 256 bits

Security Best Practices

1
Never commit secrets to version control - add .env to .gitignore
2
Use environment variables to store JWT secrets
3
Rotate keys periodically (every 3-6 months recommended)
4
Use different secrets for development, staging, and production
5
For HS algorithms, minimum key length should match algorithm (HS256 = 256 bits)
6
Consider using RS256 (asymmetric) for better security in distributed systems
7
Store secrets encrypted at rest in production
8
Use strong, cryptographically random secrets (like those generated here)
