Changelog ========= A history of what happened before, and a taste of what’s to come… Planned Future Enhancements --------------------------- * Bring back multi-threaded support * Cache time limit (force forget if a file isn’t accessed) * Don’t break backwards compatibility (again)! * Start using ECC stegfs - 2015.08.1 21st July 2016 * Fix FUSE initialisation bug (caused by update to FUSE library that was stricter than before) * Update documentation and man pages stegfs - 2015.08 13th August 2015 ---------------- * Complete rewrite **NOT BACKWARDS COMPATIBLE** - Stores block locations (and other vales) as big endian - Change key/IV processing - If you see the error message “Previous version of stegfs!” download version 2010.01 and recover your data, before creating a new stegfs and transferring your data to it - Block size is 2,048 bytes * 32 indicate the path * 1,976 are file data * 32 are a data checksum * 8 indicate the next block * All except the first 32 are encrypted; the cipher can have a block length of: - 128 bits - 192 bits - 256 bits * Allow user configured algorithm (select during mkfs) * Remove multi-threaded capability (we’ll bring it back soon) * Files are: - Read when they’re opened - Written when they’re closed - Cached until the file system is unmounted; if could be argued that keeping file contents in memory is dangerous but if you’ve mounted the file system and accessed files then this is where an attacker is likely to strike * Directories: - Still not stored - Are cached while mounted - Do not need + prefix - Do require creating on each mount (if you want to access your files) * Provide an extreme paranoia mode, where by the standard stegfs header block isn’t written, thus disguising the partition.
