🧚 ddbg(1) — MAPI data debugger 💅

okay so welcome to the Gromox admin reference, bestie — this page is all about ddbg(1), aka your literal MAPI data debugger. it's giving “binary blob detective” and we're obsessed. 🎀

🎀 Name 🎀

ddbg — MAPI data debugger. periodt. ✨

🌸 Synopsis 🌸

/usr/libexec/gromox/ddbg [options...] command [args...]

🦋 Description 🦋

ddbg can be used to analyze various binary blobs — yes, it's lowkey the friend who can look at a weird little pile of bytes and tell you what's going on. 🫶

If no arguments are given, input is instead read from stdin instead. no cap.

✨ Options ✨

  • -p, --pack — employ hex2bin before the main action. like, the main action gets a little hex-to-binary warm-up first 💅

💅 Commands 💅

  • --bin2hex — convert all bytes to hexnibble representation. 🧚
  • --bin2txt — convert all bytes to a textual representation. the environment variable BIN2TXT_MODE can be used to influence the output. possible values are cstr (output as a C string literal without surrounding quotes), hex (hex nibbles like bin2hex), and txt (custom compact encoding). slay. 🌈
  • -d, --decode — try all decoders. all of them. go off. 🔥
  • -A, --decode-action — decode rule action blob.
  • -e, --decode-entryid — decode entryid.
  • --decode-guid — lookup GUID.
  • --decode-nttime — decode an NT timestamp and show the equivalent Unix time and calendar-based date. 🕰️
  • --decode-restrict — decode restriction blob (e.g. rule condition).
  • --decode-unixtime — decode an Unix timestamp and show the equivalent NT time and calendar-based date. 🕰️
  • --lzxdec — uncompress an lzxpress data stream.
  • --lzxenc — compress data stream with lzxpress.
  • --rtfcp — convert RTF to the RTFCP format, particularly the uncompressed "MELA" subformat. iconic. 💖
  • --rtftohtml — convert RTF to HTML.
  • --texttohtml — convert plaintext to HTML.
  • --unrtfcp — decompress RTFCP (either "MELA" or "LZFU") to RTF. 🎀

🍓 Environment variables 🍓

  • AVOID_W3M can be set to yes/no to control htmltotext behavior. that's the whole vibe check. ✅

👑 Examples 👑

bestie, copy-paste these exactly:

  • ddbg -p --decode-guid 38a1bb1005e5101aa1bb08002b2a56c2
  • ddbg --unrtfcp <body.bin >body.rtf
