AppmanCC is the developer toolkit that lives next to your clipboard. Paste anything — a hash, a token, a blob of JSON, a URL — and AppmanCC recognizes it and shows the result instantly. No accounts, no tracking. ONE PASTE, THE RIGHT TOOL • Copy something, open AppmanCC and tap Paste. JSON, JWTs, hashes, UUIDs, timestamps, URLs and Base64 are detected automatically. • Results slide up from the bottom while your input stays on screen. Edit the input and the result updates as you type. • Switch tools in place, drag the panel up for more room, or down to get it out of the way. HASH & VERIFY • MD5, SHA1, SHA224, SHA256, SHA384, SHA512 side by side, plus SHA3-256, SHA3-512 and CRC32. • Paste an expected hash and AppmanCC tells you which algorithm matches — hex or Base64, any case. • HMAC with a text or hex key, UTF-8 / UTF-16LE / ASCII input, and a warning when a trailing newline would change your hash. • Hash files of any size from Files, with progress and cancel. ENCODE & DECODE • Base64 encode and decode with automatic direction, URL-safe variant, padding, MIME line breaks and data URIs. Decoded images and files can be saved. • URL encode and decode (component or full URL, %20 or +), with every part of a URL and its query parameters listed separately. • JWT decoder: formatted header and payload, issued / expiry times with a live countdown, and an on-device HS256/384/512 signature check. FORMAT & VIEW • JSON Pretty, Minify and a collapsible Tree view with search and copy-path. Your key order and number literals are kept exactly as written. • Errors point to the exact line and column, with a one-tap lenient fix for trailing commas and single quotes. • View the source of any web page with syntax highlighting, search and redirects shown. • Compare two texts by line or character, side by side or inline. CONVERT & GENERATE • Unix timestamps (seconds or milliseconds) to dates and back: local time, UTC, ISO 8601 and RFC 2822, in any time zone. • Generate UUID v4 or v7 in batches, or inspect a UUID's version, variant and creation time. • Binary, octal, decimal and hex side by side, with numbers of any size and two's complement. • Test regular expressions with live highlighting, capture groups, flags and replace preview. NETWORK TOOLS • Ping over ICMP, UDP or TCP with live statistics, payload size, don't-fragment and an audible mode. • Traceroute with per-hop times and reverse DNS names. • Port scan of common ports or any range, with service names. • Whois that follows registry referrals, or RDAP. • DNS lookups of A, AAAA, CAA, CNAME, MX, NAPTR, NS, PTR, SOA, SRV and TXT against the system or any server, with DNSSEC records, all sections and no-recursion queries. • Device info: gateway, DNS servers, external IPv4 and IPv6, proxy, and the addresses and traffic of Wi-Fi, VPN and cellular. • LAN scan: find the devices on your Wi-Fi, star the ones you care about, and keep past scans. • Speed test: latency, jitter, download and upload with live charts and a history. WORKS EVERYWHERE YOU DO • Share Extension and Action Extension: run any tool on text or files from other apps without leaving them. • Shortcuts and Spotlight actions for hashing, Base64, URL coding, JSON, JWT, timestamps and UUIDs. • Home Screen and Lock Screen widgets, and a Control Center button on iOS 18. • Pin your favorite tools and reorder them. History keeps what you copied, on this device only. • iPad keyboard shortcuts: ⌘1–⌘9 to switch tools, ⌘⇧C to copy the result, and more. PRIVATE BY DESIGN • Text tools run entirely on your device. Network tools only contact the hosts you enter. AppmanCC never reads your clipboard until you tap Paste. • No analytics, no third-party SDKs, no data collected. Secrets such as HMAC keys and JWT secrets are never saved. Questions or ideas? Write to feedback@binhua.org.
