Description

Overview:

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 (publicly available) stored fingerprint.

Computable checksums:

MD5, Adler, CRC32, SHA1, MD4, MD2, RIPE 160, SHA256 and ELF

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
• Runs under Windows 98 SE, Windows XP up to Windows Vista operating systems
