Roadmap:
* support missing segment files (chunks) * multiple platform device handle * libbfio API extensions (partial) * low and high level API - to allow low level access to sections etc. (for recovery) * lvf support - add support for interaction with data in ltree section - use libpff like item approach? * xsignature section to sign xhash and/or hash * library/tools enhancements - getoptlong * internationalisation - Unicode support (added) - locale support (partial) - multi language string support (gettext) * enhance thread safety - protect writing to internal data structures - protect reading when writing to internal data structures - thread safe functions - check for race conditions especially on change of data elements Further analysis of the EWF format: * password hash * volume/disk section (EWF-E01) - do EnCase 5 or earlier versions support 64-bit amount of sectors? - unknowns * hash section (EWF-E01) - 16 byte unknown * values in EnCase5/6 header2 (+/-) * values in ltree strings (EWF-L01 LVF) * values in session section (+/-) * amount of sectors in volume/data section has changed to a 64-bit value but what about error2/sessions ? * does newer linen6 has sha1 support? Features * resume write support for ENCASE1/SMART table sections ? * support missing segment files (chunks) * implement low memory usage option - trade off IO versus memory use Recovery and analysis: * imaging: detect disk full and ask for new segment file location? - have libewf allow to set the segment file path during write (done) - like alternative segment file path in EnCase however EnCase seems to fully test if the segment file upfront by allocating the necessary disk space * recovering corrupt EWF files (missing segment file, corrupt sections, etc.) - can the values in data be used to correct a corrupted volume ? Additional (integrity) checks: * read: check if successive headers match first header * read: add check for next and done segment - really the last segment in the file - offset pointing at themselves - correct size Possible performance improvements: * create a offset table per segment file - create it on demand - map offset table start entry from segment table as a pointer or index number ? * fill offset table while reading ? - only read first and last segment file for index build? - add offsets of other segment files when needed * tune read and write buffer sizes - read/write block size seems to have little effect for dd on average - buffered bfio ? * reduce alloc, realloc and free (this reduces breaks) use strace to analyze - pass values as parameters or use of handle - what allocation causes the break in strace of ewfacquire with compression libewf? zlib? * optimize empty block test * optimize string functions - pass length/size as much as possible * pass zero byte empty block compressed data cache as a pointer do not copy data to compressed chunk cache Error handling/tollerance * what about a function that translates error into an equivalent errno? * have wchar error messages for WINAPI? * improve offset table correction - if not correctable skip chunk while reading and mark as crc error or try to determine offset/size of chunk somehow Python bindings * rewrite pyewf to match libewf API - library module functions - handle object - keep file object for legacy support ? * implement error backtrace support in v2 API version * keep certain Python function names as alias * use Unicode strings API changes * add wide character functions definitions by default? * libbfio API extension - add means to set pools open handle limit in libewf (partial completed) - add means to obtain libbfio handle of media data in ewf - add means to set narrow string codepage - export libewf_glob_file_io_handle refactor glob functions to use libbfio handle input and return libbfio pool? think about libewf_glob_file_io_handle and abstration of file io handle get/set name * low level API - add function to retrieve the segment file names and amount? - add function to retrieve EWFX xml header/hash directly * LVF - libewf_add/remove_file for LVF * file structure API extension (idea) device handle * add Windows support for accessing memory device * detect removable disk * detect optical disk * determine optical disk sessions * detect floppy * move fstat to file_io ? * improve error detection and output (refactor error string like libbfio) * detect bus type * determine USB serial number ewftools: * add getoptlong support * log handle - implement libpff log handle * make compilation resilient for missing crypto library - compile on system without libcrypto - remove the cryptographic options if crypto library is missing * have failed on open return a more sensible error (extract from error) * ewfacquire - restrict error granularity and amount per sectors to > encase5 and > linen5 format ? no, although not set in EWF file, the granualarity is still used in handling read errors - warn if values exceed maximum segment count - adjust error granularity if error granularity < process buffer size - move ewfacquire_read_buffer to device_handle, list read errors - warn if media does not fit using chunk size or APIv1 a (32-bit) chunks size of ( 64 * 512 ) will allow up to 128 TiB - for EnCase 6 format request serial number and model if not set ? * ewfacquirestream - what about wipe on error - does this do anything? (remove if not used) - add parameter to set sector size? - allow user to set bytes per sector for raw file conversion * stream handle - implement * ewfalter - allow to set maximum delta file size default 4 GiB? * ewfexport - implement more ewfacquire acquiry parameters? - handle different input and ouput chunk sizes in low level functions build - allow different input and output header codepages? - handle ewf/raw like in smioexport - creates write only raw export file with msvscpp compilation * ewfdebug - create a tool to analyse a single segment file - implement low and high level api separation * ewfrecover - create a tool recover ewf files Windows build * windows port - some of the Windows functions are MVC 2005 or later specific - figure out a way to warn about the compiler used * add WIN32_LEAN_AND_MEAN or VC_EXTRALEAN to msvscpp * locale support - print output convert to system string - reduce string conversions, use as much as possible the system string type in the tools * ewftools check char/wchar in/output Testing * add export unattended to automated tests * add encase 6.12 sha1 support to test Deployment * debian package - implement non local libuna and libbfio support like in spec file * configure - remove enable-v1-api after testing? Known issues: * error acquiring USB floppy with bad blocks under FreeBSD - no problem with internal floppy drive virtualisation could be part of the problem * check chunk size for > 2 GiB table offsets the current assumption is that these chunks only can be uncompressed because the MSB is normally used to mark if the chunk is compressed This actually is a bug in EnCase 6.7.1 the behavior is gone in EnCase 6.8 * MS Visual Studio C++ does not allow pre compiler macro in macro definitions Work in progress: * check sprintf use - liberror -> liberror_error_vsnprintf - libewf -> libewf_hash_values, libewf_header_values - ewftools -> byte_size_string, guid * what about header values parsing with preservation of timestamps? - change localtime to gmtime in libewf_date_time_values_copy_to_string ? - force set header value to require string formatted in the date format ? * check TODO * ewfexport: fix different input and output chunk sizes for low level functions * test: read/write of EnCase 6.12 SHA1 Beta after next stable release * remove DISABLED in ewfexport * move manuals/ewfexport.1.backup to manuals/ewfexport.1 * check into resume write error

does not seem to enhance the performance significantly * ewfacquire: ask or determine media type (fixed and removable) * added EWFX format (expirimental) - (basically EWF-E01 based format) - allows for section xheader, which contains header information in XML and is stored in an compressed string 20061130 * problem with media size calculation due to change - note: uint32_t * uint32_t = uint32_t and will not upscale to uint64_t * ewf_string: better solution for size*16 in ewf_string_uncompress - the length starts out with a factor 2 and keeps increasing by a factor 2 until string can be decompressed * moved process status and summary functions to ewfcommon * added process summary to ewfexport * read: will uncompress chunk directly to chunk sized buffers for non compressed chunks * are both the segment table and section list file descriptor value needed - can this be a single value? - the file descriptor in the section list was used as safe guard only - removed * Only use the chunk cache when the input buffer size does not suffice for reading or writing an entire chunk - the chunk cache actually reduces performance for sequential reads due to additional memcpy - completed * ewfverify: show status indicator * ewfverify: when done show time and Mb/s 20061129 * Media size is calculated when not set * Added -Wextra compile flag for addition warning values * fixed: weird

table for basic offset tracking * found issues in documentation - EnCase1 (EWF-E01) format stores its chunks in the table sections not in the sectors section it uses an EWF-S01 alike layout - SMART in FTK Imager has a CRC at the end of the offset table * fixed read and write regarding issues in documentation * read: fixed error in recognizing FTK imager format 20061127 * worked on performance enhancements * changed ewf_crc_calculate to make use of zlib's adler32 function instead of algorithm derived of CRC algorithm by Andrew Rosen - this improves the performance significantly ;-) *

char and wchar_t * change char* to EWF_CHAR* or LIBEWF_CHAR* - allow for char and w_char interfacing with library - use LIBEWF_CHAR for char/w_char wrapping and EWF_CHAR for byte strings in EWF file format, CHAR_T required for wchar_t support in basic functions - make internal EWF related strings byte strings (EWF_CHAR) - make string functions safe to be char or uint8_t - use string.x for string functions * string: added length to libewf_string_search * string: added length to libewf_string_split * ewfacquire: added wchar_t support for utsname_buffer.sysname * ltree: changed ewf_tree_data_read * ewfinfo: added stored MD5 hash * ewfacquire: added print read errors on exit * all: in read and write functions add file_descriptor test - not necessary libewf_common functions do check this 20061122 * worked on string and char types * windows has: wmain for wide character arguments * moved getopt code to ewfgetopt for wmain support * moved glob code to ewfglob * changed libewf_open to match main and getopt type arguments * fixed check enable...=no validation - $withval needed to be $enableval * added CHAR_T and INT_T for wrapping character type of support functions

moved section reading and writing code to libewf_section * fixed bug in libewf_read_random when offset is too large * wraped basic library calls in preperation of thread safety of library calls * added prefix to functions in libewf_common with common_ * enhanced error handling - no program exit but a nice return * using typedefs instead of defines * due to 20060505 fix, gave all value definitions a default value * removed a large amount of unrequired includes 20060902 * worked on code clean up and improved error handling * libewf_handle_cache_realloc removed from read volume section function * endian functions are prepended with libewf_endian_ * the secondairy offset table in handle for S01 format will no longer be allocated for read * started on error tollerance levels for recovery * moved file descriptor check in last_offset calculation to do one check per section list - section list was altered to be used for a single segment file only - reduces memory requirements 20060831 * worked on code clean up and improved error handling * created seperate structure for chunk cache 20060830 * worked on code clean up and improved error handling * allow to set clean value in libewf_(re)alloc_cleared functions 20060829 * worked on code clean up and improved error handling * worked on libewf_string - moved split code to it 20060828 * worked on code clean up and improved error handling * introduced and fixed new bug - reminder do not free result from localtime() 20060826 * worked on code clean up and improved error handling * fixed realloc calculation bug in file_read * moved definitions from .h files * changed headers in all files 20060824 * worked on code clean up and improved error handling * move crc check from file_read into different EWF read methods? no embedding this check in the segment types makes it more difficult to generate an CRC error list for ewfinfo 20060823 * no need for fatal warnings if code becomes re-entrant after error * added a wrapper of basic library calls * worked on code clean up and improved error handling * renamed notify.* to libewf_notify.* prevents name clashes * ewf_crc function now use a dynamic allocated CRC - this helps with error propagation * added big endian support to ascii to utf16 routine 20060822 * added byte swap (equivalent of dd conv=swab) functionality in both read and write * changed sys/types.h to inttypes.h all: check if sys/types definitions still needed in ewf_*.h files ? - not under linux will do a cross platform test anyway * started with implementing improved error handling and re-entry after error, combined with code clean up, better error control, revision of header to allow for one place to maintain acknowledgements 20060821 * read: added basic support for L01 files, which are basically EWF files * renamed ewf_file_signature to evf_file_signature - closer to the truth * ewfacquire: compensate for maximum S01 file size in ewf file size question - determine maximum - not relevant because there is a maximum of chunks within the file but the other data could grow to the 2 GiB 20060820 * ewfacquire: small change to confirmation 20060819 * lifted the 255 segment file limit on write, however it uses an (horrible) increment based naming scheme much like EnCase write: allow more than 255 segment files - completed * write: worked on SMART (EWF-S01) support * write: SMART (EWF-S01) - build in support for table2 * all: add SMART support - complete * worked on - all: due to 20060505 fix give all value definitions a default value - looks nicer * due to changes to the read and write logic the library was retested * read: error in percentage in libewf_read_random - works on FC5 * table size limitation does not seem present in EWF-E01 only in EWF-S01 * use autoconf/automake cross compilation parameters for platform determination - completed 20060818 * read: worked on SMART (EWF-S01) support * alternative read method was removed, the assumption it was based on is no longer valid read: remove alternative read method the assumption behind is fails for the SMART format - completed * renamed alternative write method to wipe block on read error write: rename the alternative write method to wipe_block_on_error (or something) - completed * read random: chunk based size check now is a buffer based size check * removed handle->chunk_crc no longer needed * for the EWF-S01 format the entries in table2 are appended to the offset table - have yet to test a file with a table2 section * write: worked on SMART (EWF-S01) support 20060817 * read: worked on SMART (EWF-S01) support 20060816 * ewfacquire: add overview to confirm user input, otherwise restart input query - completed * ewfacquire: make encase5 file option default - completed * fixed incorrect order for values in header2 on write - also in documentation 20060812 * made the amount of read error retries flexible and user adjustable through ewfacquire * correction of "int result" in file_write to be C89 code compliant * new file size algorithm to fill up closer to max file size when compressing write: change algorithm to fill files upto file size - completed * added empty block compression write: always compress empty chunks - completed as an option 20060809 * fixed size bug for large images on Cygwin - fix of 20060610 not sufficient for Cygwin * fixed invalid value in printf volume read verbose messages * added autoconf/automake structure 20060708 * renamed endian.h to libewf_endian.h for compatibility issues 20060617 * put conditions around debug code in eqfacquire 20060611 * fixed - one off bug in header value end of string 20060610 * ewfacquire test on multiple platforms * added support for SMART format volume section - equals the original EWF volume section definition * fixed - type casting error in data size * fixed - missing header for encase1 format in write * fixed - bug in writing encase4 and encase5 header2 in write - error in ascii to utf16 routine * fixed - bug in writing encase4 and enacse5 header in write - logical formatting error * write: timestamp is now generated only once * write: fixed incorrect free in header values * write: fixed memory corruption bug in ewfacquire - required explicit zero of string 20060605 * fix of data corruption bug - one off * ewfacquire: sanitize input provided by user * ewfinfo/eqwfacquire ? 1970 date when no case data is provided - bug in split function regarding first empty value * removed file cache - no longer required 20060527 * started analysis of a data corruption bug 20060526 * fixed write bug when read is successful after error with small error granualirity * fixed write bug with error granularity 1 * ewfacquire: add chunk size input possibility * ewfacquire: add error granularity size input possibility * ewfacquire: memory corruption bug in user input - repaced some code - looks OK now - but hard to reproduce * fixed write bug with block size 128 error granularity 16 in test * write: improve reading of bad sectors and writing a error2 section to file for encase5 file option 20060520 * fixed media size bug - old method of calculation was still in there :-( * worked on ewfacquire read on error * added alternative write method to test acquired images against existing tooling * ewfaquire: able to produce exact media data as linen * write: what if read error is in last chunk and it is smaller than chunk size !? 20060517 * removed duplicate include from notify.c 20060516 * added media size to ewfinfo * worked on ewfacquire read on error 20060513 * minor adjustment in libewf.h - ewf_close renamed to libewf_close 20060505 * Fix for older compilers like gcc 2.95 - rewrite to older C statements 20060424 * added warning macro to allow overriding some fatal errors * allow overriding invalid CRC's * refactored crc check in ewf_section to file_read - for scope of handle and uniformity within the code * further analysis of unknown values in hash section - also found difference in signature value Encase4 and Encase5 20060423 * Fix for Solaris in definitions.h 20060422 * Fixed missing PRI definitions on OpenBSD - now defines in definitions.h * changed sprintf to snprintf * added device size determination for OpenBSD * fixed bug in header values parsing for empty first value empty * added compression level definition * ewfinfo: add compression media information in ewfinfo - Encase5 format only * write: moved compression type functionality from ewfacquire into library 20060419 * Adjusted write method - to fix filesize problem * Correction of verbose print of last chunk number * the write function works only when a data section is at the start of the file - why ? not a bug in write but in read the first offset in the segment table was filled with 0 instead of 13 which is the size of the file header 20060418 * Tested on FreeBSD 6.0 needed to add include header in ewf_sectors.h * Adjusted Make to be more generic and to work on FreeBSD 6.0 20060415 * changed u_int to uint * removed LIBEWF_ types * zlib uses a long which varies per 32 and 64 bit architecture using an intermediate variable fixes not able to read compressed images on a x86_64 architecure * Memory corruption bug in segment table filename fixed 20060414 * Fixed previous offset size * removed memcpy assignments * type fixed malloc assignments * removed (void *) from memset * reduced the amount of int definions * changed printf formaters * added status indication to ewfexport using callback function in read_from_file_descriptor * added quiet option
