Hexdump API
Produce a canonical hex dump of any input and parse a hex dump back into bytes. The dump endpoint formats data the way hexdump -C and xxd do — an offset column, the bytes in hex (grouped in eights), and a printable-ASCII gutter — with a configurable number of bytes per line and optional uppercase. Feed text as UTF-8, or binary as hex or base64. The parse endpoint reverses any hex dump — tolerating offset columns and ASCII gutters, or a plain run of hex — and returns the reconstructed bytes as hex, base64 and (when printable) text. Perfect for inspecting binary payloads, debugging protocols and file formats, diffing buffers and teaching. Pure local computation — no key, no third-party service, instant; up to 1 MB via POST. Live, nothing stored. 3 endpoints. Distinct from a plain base64/hex encoder.
