About JWT Keys
Key Types
HMAC: Symmetric keys for HS256, HS384, HS512
RSA: Asymmetric key pairs for RS256, RS384, RS512
EC: Elliptic curve key pairs for ES256, ES384, ES512
Security Best Practices
• Use strong, random keys
• Store keys securely
• Rotate keys regularly
• Use appropriate key lengths
• Never commit keys to version control
