Checksum compute different file checksums (Hash / Message digest)

Arpoon Checksum is a lightweight software application that helps you calculate a file's checksum. 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.

Arpoon Checksum can be used 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.

Here are some key features of "Arpoon Checksum":

· 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
