Masquerade: A Quiet Toolbox

Masquerade is a quiet toolbox for builders.

Twenty-eight converters, formatters, and inspectors crafted for the data you carry every day. Fast, copy-friendly, and typeset with editorial restraint in IBM Plex.

CORE TRANSFORMATIONS
• JSON, YAML & TOML — Pretty-print, minify, browse interactive trees, and convert between structured formats.
• Timestamps & Epoch — Convert between Unix seconds/milliseconds and ISO 8601 with relative time breakdowns.
• JWT Decoder — Decode headers and payloads, with expiration and not-before indicators. It does not verify signatures.
• Number Base & Bytes — Move between Hex, Binary, Octal, Decimal, and UTF-8 byte arrays.
• Base64 & Text Case — Encode, decode (standard & URL-safe), and convert identifiers across camel, snake, kebab, and pascal cases.
• CSV / TSV — Bidirectional conversion with JSON and bounded table previews.
• Color & Contrast — Translate HEX, RGB, HSL, and OKLCH with WCAG 2.1 contrast ratio scoring.
• Basis Points & Math — Basis points (bps) ↔ % ↔ decimal, plus mathematical expression evaluation.

DEEP INSPECTORS & SECURITY
• Log & Stack Trace Inspector — Group, search, redact, and parse JSON Lines, raw server logs, and stack traces.
• Environment & Config — Normalize, compare, and redact .env files, properties, and configuration headers.
• X.509 Certificates — Inspect local PEM/DER certificates, chains, fingerprints, SANs, and public keys without remote requests.
• Unicode & Strings — Reveal grapheme clusters, code points, UTF-8 bytes, invisible bidi controls, and line endings.
• Artifact Inspector — Recursively trace nested encodings with bounded previews.
• HTTP Inspector — Inspect, format, and redact curl commands and raw HTTP request snippets.

GENERATION & VALIDATION
• UUID & ULID — Generate v4/v7 UUIDs, validate versions/variants, and parse ULIDs.
• IP & CIDR — IPv4/IPv6 subnetting, host ranges, broadcast addresses, and network scope flags.
• Regular Expressions — Test Dart regex patterns with real-time match highlighting and capture group inspection.
• Text Diff — Side-by-side and unified diffs with line- and word-level granularity.
• Hashes & Checksums — MD5, SHA-1, SHA-256, and SHA-512 with verification mode.
• QR Codes — Scan with the camera or generate codes locally.
• Password & Token Generator — Generate crypto
