NAME
     ewfverify -- verifies media data stored in	EWF files

SYNOPSIS
     ewfverify [-A codepage] [-d digest_type] [-f format] [-l log_filename]
	       [-p process_buffer_size]	[-hqvVwx] ewf_files

DESCRIPTION
     ewfverify is a utility to verify media data stored	in EWF files.

     ewfverify is part of the libewf package.  libewf is a library to access
     the Expert	Witness	Compression Format (EWF).

     ewf_files the first or the	entire set of EWF segment files

     The options are as	follows:

     -A	codepage
	     the codepage of header section, options: ascii (default), win-
	     dows-874, windows-932, windows-936, windows-949, windows-950,
	     windows-1250, windows-1251, windows-1252, windows-1253, win-
	     dows-1254,	windows-1255, windows-1256, windows-1257 or win-
	     dows-1258

     -d	digest_type
	     calculate additional digest (hash)	types besides md5, options:
	     sha1, sha256

     -f	format
	     specify the input format, options:	raw (default), files (re-
	     stricted to logical volume	files)

     -h	     shows this	help

     -l	log_filename
	     logs verification errors and the digest (hash) to the log file-
	     name

     -p	process_buffer_size
	     the process buffer	size (default is the chunk size)

     -q	     quiet shows minimal status	information

     -v	     verbose output to stderr

     -V	     print version

     -w	     zero sectors on checksum error (mimic EnCase like behavior)

     -x	     use the chunk data	instead	of the buffered	read and write func-
	     tions.

ENVIRONMENT
     None

FILES
     None

EXAMPLES
     ewfverify can either verify the raw storage media data or logical file
     data stored in EWF	file(s).

   To verify the raw storage media data:
     # ewfverify floppy.E01
     ewfverify 20110801

     Verify started at:	Tue Jan	11 19:21:51 2011

     This could	take a while.

     Status: at	2%.
	     verified 32 kB (32768 bytes) of total 1.4 MiB (1474560 bytes).

	   ...

     Status: at	100%.
	     verified 1.4 MiB (1474560 bytes) of total 1.4 MiB (1474560	bytes).
	     completion	in 1 second(s) with 1 MiB/s (1474560 bytes/second).

     Verify completed at: Tue Jan 11 19:21:52 2011

     Read: 1.4 MiB (1474560 bytes) in 1	second(s) with 1 MiB/s (1474560	bytes/second).

     MD5 hash stored in	file:	   ae1ce8f5ac079d3ee93f97fe3792bda3
     MD5 hash calculated over data:	     ae1ce8f5ac079d3ee93f97fe3792bda3

     ewfverify:	SUCCESS

   To verify logical file data:
     # ewfverify -f files logical.E01
     ewfverify 20110111

     Verify started at:	Tue Jan	11 19:21:51 2011

     Single file: file1.txt
     MD5 hash stored in	file:		     6fef2a64afbf070a264366183698bb5e
     MD5 hash calculated over data:	     6fef2a64afbf070a264366183698bb5e

	   ...

     Verify completed at: Tue Jan 11 19:21:52 2011

     ewfverify:	SUCCESS

DIAGNOSTICS
     Errors, verbose and debug output are printed to stderr when verbose out-
     put -v is enabled.	Verbose	and debug output are only printed when enabled
     at	compilation.
