	FlyingBit Hash Calculator  License: Freeware
	FlyingBit Hash Calculator is an add-in for the OS shell allowing you to find out the hash sum of any file right from the context menu of the system. Now you do not have to run a special program, select the Open menu item and then search for the necessary file. You can find out the hash sum right in Explorer! Moreover, the program can compare MD5 sums with *.md5 files of the GNU MD5Sum tool and also create its own *.md5 files.    FlyingBit Hash Calculator calculates the hash sum using about 9 different algorithms among which there are such popular algorithms as MD5, CRC32 or SHA1 and less popular ones, for example, TIGER. And the use of *.md5 files is the standard for confirming the validity and integrity of a file.    Main features:   * Easy to use   * Small size   * Customizable settings   * Supporting all popular algorithms   * Supporting *.md5 files   * Compatibility with GNU MD5Sum Author: FlyingBit Software| Date: 19-03-2008 | Size: 288 KB

	FSUM  License: Freeware
	Free command line utility for file multi-checksum generation and verification. It allows to create/verify popular file hashes/checksums: MD2, MD4, MD5, SHA-1, SHA-2(256,384,512), RIPEMD-160, PANAMA, TIGER, CRC-32, ADLER32, and the message digest used in eMule/eDonkey (ed2k) software. Its most common use is checking files for corruption (data integrity checking). A hash/checksum calculation might be performed on data before transferring (downloading/uploading) it from one location to another. Making the same calculation after the transfer (download/upload) and comparing the former and latter results, you can check if the received data is corrupted or not. FSUM notifies about any bad, incorrect, missing file. It is a very fast, easy to use tool. Allows to recurse directories. Works with large size files. Supports .MD5 and .SFV file formats (automatically recognizes the format when verifying). Compatible with md5sum, MD5Summer, Easy MD5 Creator, SFV Checker/Verifier, WinSFV, Win CRC32.

	HashCalc  License: Freeware
	Free calculator to compute multiple hashes, checksums and HMACs for files, text and hex strings. It allows to calculate hash (message digest), checksum and HMAC values based on the most popular algorithms: MD2, MD4, MD5, SHA1, SHA2 (SHA256, SHA384, SHA512), RIPEMD160, PANAMA, TIGER, CRC32, ADLER32, and the hash used in eDonkey (eDonkey2000,ed2k) and eMule tools. It supports 3 input data formats: file, text string and hexadecimal string. It is a very fast, easy to use and to install application. It works with large size files, supports file drag-and-drop functionality. HashCalc generates hash, check sum, and HMAC for files of any type which makes it a valuable utility to test for corruption your FTP and other download/upload transfers.

	Arpoon Checksum  License: Freeware
	Arpoon Checksum computes checksums of files. A checksum (message digest, hash value) is a kind of fingerprint that enables to uniquely identify a file or document. This can be used for authentication purposes or to track document modifications. By way of example, this tool can be utilized to: * uniquely identify a given file, thus using the checksum as a fingerprint. * survey a file i.e. to check if a file as been modified by comparing its actual checksum with a previously archived value. * look for possible duplicate of files by scanning hardware storage devices (hard disk, DVD, CD, memory sticks...) * verify the authenticity i.e. genuineness of a fingerprinted document that has been sent to you (e.g. as an EMail attachment or by way of a download) by comparing its on-the-fly computed checksum with its stored fingerprint. Builtin functionality: * Drag&Drop of files or directories * Recursive calculation for directories strucutres (optional) * Result list can be sorted (ascending/descending) by every single checksum type * Link to files can be resolved (optional) * Hash values can be displayed as hexadecimal or as a MIME-compatible base64 code * Display of detailled file properties like attributes, size, date of creation... * Result list may be exported to the clipboard or saved as CSV or HTML files * During long run calculation, the computing progression is displayed * Statistics on computation (average speed rate, file size ...) are automatically collected * A warning message may be displayed before a time consuming computation is started * Multiple files computation may be aborted during the calculation * Checksum calculation for a very big files may be aborted too * All options are maintened in an Ini-file, which is automatically saved in the current user's application data directory, allowing a per user configuration Author: Arpoon - Loïs Bégué| Date: 05-08-2007 | Size: 482 KB

	GSplit  License: Freeware
	GSplit is a free original file splitter that lets you split your large files (like compressed archives, multimedia, song, music, movie, backup, Zip, picture, log, large text and document files...) into a set of smaller files called pieces. These pieces are easier to copy or backup to floppies, CD, DVD, USB or any disk; to send by email or upload with file hosting services (forget size restrictions!); to share with friends, colleagues or to distribute to other users through networks and the Internet. In addition to the features of other standard file splitters, GSplit can: - create two types of pieces: disk spanned and blocked (specific size). Either enter the size for each piece file, the number of pieces to create or the number of lines / occurrences of a pattern by piece. - generate small Self-Uniting programs (.exe) so anyone without GSplit can assemble pieces and restore the original file. The appearance and functionality of these programs can be customized. - split very large files (bigger than 4 GB) or small files (less than 100 kb). - restore file properties: file date, attributes are not lost. - perform fast checks to detect file corruption (size, offset, CRC32) and to assure that files are successfully restored by users. - customize piece files according to your needs (size, filenames, title, author...), leave additional space on disks... - split large text and similar files like huge server log files by number of lines or occurrences of a specified pattern. - support splitting multiple files in one time, work with batch (automating) and command line options. - store settings into profiles (XML) for possible reuse. - support GUI skins. - integrate Windows Explorer (split files with the context menu). GSplit finally features an intuitive user interface that makes operations easy and fast, has multilanguage support, and provides you with advanced options for pieces and Self-Uniting executable files... GSplit lets you split any file in a snap. Author: G.D.G. Software SARL| Date: 14-04-2007 | Size: 1360 KB
