ewfverify(1) - Linux man page

Name

ewfverify - verifies media data stored in EWF files

Synopsis

ewfverify [-A codepage] [-d digest_type] [-l log_filename] [-p process_buffer_size] [-hqvVw] 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 support the Expert Witness Compression Format (EWF). libewf supports both the SMART format (EWF-S01) and the EnCase format (EWF-E01). libewf currently does not support the Logical Volume format (EWF-L01). EWF-X is an expirimental format intended for testing purposes to enhance the EWF format. libewf allows you to read and write media data in the EWF format.

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), windows-874, windows-1250, windows-1251, windows-1252, windows-1253, windows-1254, windows-1255, windows-1256, windows-1257, windows-1258

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

-h' shows this help

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

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

-q' quiet shows no status information

-v' verbose output to stderr

-V' print version

-w' wipe sectors on CRC error (mimic EnCase like behavior)

Environment

None

Files

Diagnostics

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