JWT Decoder

Decode a JSON Web Token's header and payload and read its timestamps.

Decoded locally. The signature is not verified (that needs the secret/key, which never leaves a server).
Header
{
  "alg": "HS256",
  "typ": "JWT"
}
Payload
{
  "sub": "1234567890",
  "name": "Gentoo Penguin",
  "iat": 1700000000,
  "exp": 1900000000
}
