✨ RSYNCRYPTO_RECOVER 💖

okay bestie, welcome to the rsyncrypto_recover manual — it's part of the Rsyncrypto_recover User Manual, and no cap, it's a tiny little rescue mission of a program. 🦋

🌸 NAME 🌸

rsyncrypto_recover — recover all usable data from corrupted rsyncrypto filemaps 💅

✨ SYNOPSIS ✨

rsyncrypto_recover badfile > goodfile

like. that's it. that's the whole vibe. redirect it and go 🎀

💖 DESCRIPTION 💖

This manual page documents the rsyncrypto_recover command. (yes bestie, a manpage for the manpage-adjacent thing, we love a self-aware moment ✨)

So here's the lore 👑: when you run the rsyncrypto command with the --name-encrypt option, it builds a file that maps your plain text representation over to the encrypted file names. That file mapping has a strict format — it's records, and the records are delimited by a NULL byte. very structured. very demure. 🎀

Now 😭 a bug showed up in version 1.07 of rsyncrypto (rip) and it got fixed in version 1.09. This bug made that file get somewhat corrupted under certain circumstances — most notably when you used the --delete-keys command line option. it's giving chaos, honestly 💀

but wait — important!! the only records that got corrupted are records that were due to be deleted anyway. so ngl, this bug did not result in any loss of actual important data. periodt. 🫶

What it did do though? It left behind a file that rsyncrypto then straight up refused to open. rude. 🙈

Enter rsyncrypto_recover: it reads in a file map, and outputs to standard output only those records that are valid. that's the whole job. icon, honestly. 👑

🌈 PARAMETERS 🌈

  • badfile — a file map that contains some good records and some corrupted records. a little bit of a mess, a little bit of treasure. we're salvaging the treasure 💖
