XHelper vs Hash Calculator MD5 SHA256

XHelper is a fast, private toolkit for the small conversions developers do all day. Paste anything and XHelper recognizes it — a JWT, JSON, a Unix timestamp, a UUID, a URL, a color, a number, or Base64 — and opens the right tool with your input already filled in. ENCODING • Base64 — Encode and decode text and files, with a URL-safe option and image previews for decoded data. • URL — Percent-encode and decode, and see every part of a URL plus its query parameters. • JWT — Decode the header, payload and claims, see when a token expires, and verify HS256, HS384 and HS512 signatures. HASH • MD5, SHA-1, SHA-256, SHA-384 and SHA-512 for text or files, with optional HMAC. Large files are hashed in chunks. FORMAT • JSON — Pretty-print with 2 spaces, 4 spaces or tabs, minify, sort keys, and get errors with the exact line and column. GENERATE • UUID — Create v4 or time-ordered v7 UUIDs in batches, with uppercase, hyphen and brace options. Inspect any UUID, including the timestamp inside a v7. CONVERT • Epoch — Unix timestamps in seconds, milliseconds, microseconds or nanoseconds to UTC, local time, ISO 8601 and relative dates, and back again. • Number Base — Binary, octal, decimal and hex, including negative numbers. • Color — Hex, RGB and HSL, plus ready-to-paste SwiftUI, UIKit and AppKit code. TEXT • Regex Tester — Live match highlighting, capture groups and flags. • Text Diff — Compare two blocks of text line by line. • Text Tools — camelCase, snake_case, kebab-case and more; sort, reverse and de-duplicate lines; count characters, words, lines and bytes. WORKS EVERYWHERE • Shortcuts, Siri and Spotlight — Encode and decode Base64 and URLs, hash text, format JSON, decode JWTs, generate UUIDs, convert timestamps and change case without opening the app. • Mac Services — Select text in any Mac app and use Services → XHelper to encode, decode, format JSON or change case in place. • A native app for Mac, iPhone and iPad, with a searchable sidebar and keyboard shortcuts on Mac. PRIVATE BY DESIGN XHelper works completely offline. Nothing you paste ever leaves your device, and there's no tracking of any kind.

Need a hash calculator that just works? HashCalc computes MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 the instant you type or paste — no upload, no wait, no guessing. Most "hash" tools send your text to a website or bury the digest you need under ads. HashCalc runs every algorithm locally on your device and shows the results side by side, so you can copy the exact digest you want and move on. WHAT YOU GET - Live digests for MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 as you type - Verify a download in one step: paste the expected checksum and see match or mismatch instantly - Compare two hashes side by side to confirm two files or strings are identical - Sign messages with HMAC using your secret key across the full SHA family - Checksum any file — HashCalc streams it through the hasher so even large files hash cleanly - A saved history of recent hashes plus a plain-language reference on MD5, SHA, CRC32 and HMAC PERFECT FOR - Developers signing API requests and webhooks with HMAC - Anyone verifying a downloaded ISO, installer or backup against its posted checksum - Security-minded users checking file integrity without touching the cloud - Students and learners who want to see how hashing actually works WHY NOT JUST USE A WEBSITE? Web hashers make you paste sensitive text into a server you don't control, and they break the moment you lose signal. HashCalc computes everything on-device, works fully offline, and never sends your input anywhere. PRIVACY Every digest is computed on your device. No accounts, no servers, no tracking — your text and files never leave your phone. FULL ACCESS The free app covers core hashing. A HashCalc membership unlocks everything: all six algorithms, verify and compare, HMAC signing, file hashing and saved history. Choose a weekly or yearly plan, or a one-time lifetime purchase — subscriptions renew until cancelled and can be cancelled anytime. Type your first string and watch the digests appear.
