软件包: dcfldd (1.7.1-1)

enhanced version of dd for forensics and security

dcfldd was initially developed at Department of Defense Computer Forensics Lab (DCFL). This tool is based on the dd program with the following additional features:

 - Hashing on-the-fly: dcfldd can hash the input data as it is being
   transferred, helping to ensure data integrity.
 - Status output: dcfldd can update the user of its progress in terms of the
   amount of data transferred and how much longer operation will take.
 - Flexible disk wipes: dcfldd can be used to wipe disks quickly and with a
   known pattern if desired.
 - Image/wipe verify: dcfldd can verify that a target drive is a bit-for-bit
   match of the specified input file or pattern.
 - Multiple outputs: dcfldd can output to multiple files or disks at the same
   time.
 - Split output: dcfldd can split output to multiple files with more
   configurability than the split command.
 - Piped output and logs: dcfldd can send all its log data and output to
   commands as well as files natively.
 - When dd uses a default block size (bs, ibs, obs) of 512 bytes, dcfldd uses
   32768 bytes (32 KiB) which is HUGELY more efficient.
 - The following options are present in dcfldd but not in dd: ALGORITHMlog:,
   errlog, hash, hashconv, hashformat, hashlog, hashlog:, hashwindow, limit,
   of:, pattern, sizeprobe, split, splitformat, statusinterval, textpattern,
   totalhashformat, verifylog, verifylog:, vf.
