Security tools help developers work with cryptographic primitives and authentication tokens. The Hash Generator computes MD5, SHA-1, SHA-256, and SHA-512 digests using the Web Crypto API — ideal for verifying file integrity, comparing checksums, or understanding how different algorithms behave. The JWT Decoder parses JSON Web Tokens into their header, payload, and signature components, displays registered claims (iss, exp, iat), and checks expiration — all without sending the token to any server.
