Perguntas frequentes
What does the 'alg' field in the JWT header mean?
The 'alg' field specifies the cryptographic algorithm used to sign the token. Common values include HS256 (HMAC with SHA-256, symmetric), RS256 (RSA with SHA-256, asymmetric), and ES256 (ECDSA with P-256, asymmetric). The verifying party must use the same algorithm and corresponding key to validate the signature.
