HxD is a carefully designed and fast hex editor including raw disk editing, modifying foreign RAM and handling files of any size HxD is a carefully designed and fast hex editor including raw disk editing, modifying foreign RAM and handling files of any size.
Its clear interface offers searching/replacing, exporting, checksums/digests, insertion of byte patterns, a file shredder, concatenation or splitting of files, statistics and more.
Editing works like in a text editor with functions streamlined to hide differences that are purely technical.
For example you can view a drive just as one stream, can open it under Windows 9x or Windows NT+, undo, search, save, export or whatever you could do with a file.
There is no sector-limited editing that gets in your way. The same holds true for the file size (also > 4 GB), which doesnt affect editing speed and still supports undo.
Or have a look at the RAM-editor that supports data-folding on every memory section and hides by default inaccessible memory, for a better overview but keeps the real offsets.
HxD also features a reliable checksum generator.
Main features:
- Instant opening regardless of file-size (>4GB is no problem: opening, editing are very fast)
- Fast searching: forward, backwards or from beginning
- Replace function (fast even for millions of edits)
- Search and replace support Unicode, Ansi-text and Hex-values
- Disk-Editor: RAW reading and writing of disks and drives (hard disks, floppy disks, USB-disks, CD-ROM, ...) for Win9x, WinNT and higher
- RAM-Editor: can read and write virtual memory of other processes
- Data-folding for better overview in RAM-Editor
- Exporting of data to source code (Pascal, C, Java) or as formatted output (plain text, HTML, Richtext, TeX) or to hex formats:
- Motorola S19 Records, Motorola S28 Records, Motorola S37 Records, 16 Bit Intel Hex, 20 Bit Intel Hex, 32 Bit Intel Hex
- Checksum-Generator: Checksum-8, Checksum-16, Checksum-24, Checksum-32, CRC-16, CRC-16 CCITT, CRC-32, Custom CRC, SHA-1, SHA-256, SHA-384, SHA-512, MD-2, MD-4, MD5
- Insertion of byte patterns
- File shredder for safe file deletion
- Splitting or concatenating of files
- File compare (simple)
- Statistical view: Graphical representation of the character distribution. Helps to identify the data-type of a selection.
- Support for ANSI, DOS/IBM-ASCII, EBCDIC and Macintosh charsets
- Byte grouping (1, 2, 4, 8 or 16 bytes packed together in one column)
- Hex only or text only mode
- Progress-window displays on long time operations (shows remaining time and has a cancel-button)
- Unlimited undo
- Modified data is highlighted
- Internet update checker
- Easy to use interface with modern icons
- Ghost caret: displayed around the corresponding character/hex value on the inactive column, the caret is placed on the active column
- Goto address
- Printing
- Overwrite or Insert Mode
- Cut, Copy, Paste Insert, Paste Write
- Clipboard support for other hex editors (Visual Studio/Visual C++, WinHex, HexWorkshop, ...)
- Bookmarks: Ctrl+Shift+Number(0-9) sets a bookmark, Ctrl+Number(0-9) goes to a bookmark
- Navigating to nibbles with Ctrl+Left or Ctrl+Right
- Flicker free display and fast drawing

ReHash is an easy-to-use console-based hash calculation tool written in standard C++ ReHash is an easy-to-use console-based hash calculation tool written in standard C++. It may be freely distributed and modified under the terms of the BSD open source license.
It supports many algorithms, for example Adler32, CRC-16, CRC-16-CCITT , CRC-16-XMODEM, CRC-32, ELF-32, FCS-16, FCS-32, FNV-32, FNV-64, GHash-32-3, GHash-32-5, GOST-Hash, HAVAL (3/4/5, 256), MD2, MD4, MD5, SHA-1, SHA-256, SHA-384, SHA-512, Size64, Tiger, XUM32. For a full list see the ReHash documentation manual (included in downloadable package).
It is possible to compute HMACs of all algorithms.
The tool can output the hashes in various formats like plain text, HTML, XML and CSV.
ReHash can be fully configured using some of the many command-line arguments which can be passed to the tool. You can selectively activate/disable hash algorithms and set scanning options like scanning subdirectories recursively and excluding/including files using advanced file pattern matching.
