- 资源ToolJWT DecoderInspect a JWT — header + payload, issued/expiry badges. Decode-only, no verification. Quickly check what claims a token carries without spinning up a curl + Python one-liner.
- 资源ToolUUID GeneratorGenerate v4 UUIDs via crypto.randomUUID(). Bulk mode up to 500, copy individual rows or the full batch. Seeding fixtures, naming buckets, or stamping migrations — UUIDs you trust without leaving the page.
- 资源ToolPassword GeneratorRandom passwords via crypto.getRandomValues. Tune length, character classes, ambiguous-char avoidance, with a live entropy meter. Local generation only — bytes never leave the browser. The strength bar is informative, not theatrical.
- 资源ToolHash GeneratorSHA-1, SHA-256, SHA-384, SHA-512 via SubtleCrypto. Live-updates as you type. Checksumming a string or sanity-checking a server-side hash without reaching for a CLI.
- 资源ToolRandom NumberCryptographically unbiased random integers via crypto.getRandomValues with rejection sampling. Bulk + unique modes. Math.random with a modulo is fine for dice; for anything else, you want true uniform sampling.
