jwt-decode

Overview

Decodes a JWT and inspects its claims without needing the signing key. Base64URL-decodes header and payload, parses standard claims (iss, aud, sub, exp, iat, nbf, jti), and reports algorithm, key id (kid), token type (typ), TTL, and clock-validity (is_expired / is_not_yet_valid / is_currently_valid_by_clock). Does NOT verify signatures — for inspection only, never trust output for auth decisions. Use it as a JWT parser, JSON Web Token inspector, Bearer token debugger, OAuth ID-token reader, or A
