hexdump.nx

hexdump.nx -- xxd-style byte buffer dump. Produces human-readable byte listings like: 00000000: 4865 6c6c 6f2c 2057 6f72 6c64 210a Hello, World!. 0000000d: 4e69 7368 690a Nishi. Used for: debugging crypto outputs, network packet dumps, IR inspection, anything where hex + ASCII side-by-side is the right debug lens. Format (xxd default): <8-hex offset>: <8 pairs of 2-hex bytes, space between pairs> <ASCII> Bytes 0x20..0x7E render as themselves; others as '.'. 16 bytes per row. Invariants: HD1 Output is deterministic: same input bytes -> same output. HD2 ASCII column padded so rows align visually -- last row with <16 bytes left gets padding spaces. HD3 Offsets are 8 hex digits (fits up to 4 GiB; enough for every realistic buffer).
