Listed in categories: Executable CRC Calculators

Most recent version:
1.6.2

Most recent release date:
December 29, 2009

Description:
Portable file checksum verifier that allows you to calculate many file checksums (hashes) and compare them with original one. Thanks to its simplicity and portability, it aims to be a portable, versatile and "must have" tool for dealing with single files and their checksums - to calculate, compare and verify them.

Marxio FCV supports major checksum types:
- CRC32,
- MD4,
- MD5,
- SHA1,
- SHA-256,
- SHA-384,
- SHA-512,
- RIPEMD-128,
- RIPEMD-160,
- HAVAL 256,
- TIGER 192.

"Drag and drop" function - all you need to to is to drag a file from Windows Explorer onto the form to calculate selected checksum type.

Context menu - optional integration with Explorer context menu with Your custom text and defined selected checksum to calculate

Compare checksums - with other selected checksum.

Large files support - with size over 32 GB.

Very fast - calculate 4 GB large DVD file/image in 2 minutes using md5 algorithm.

Portable version - one-file program, just one executable file.

Interface - simple, eye friendly with mini-form available.

Keyboard shortcuts - as much handy shortcuts as possible, even for copy and paste checksum from clipboard

Save checksum to file - checksum and filename.

History - save all calculated checksums to file.

Additional settings - stay-on-top, save windows position and last used checksum type, show mini-form, show hashes in upper or lowercase, break function, high contrast themes support, log file, snap to edge - all are configurable.

Frequent updates - new releases published even a week !

Vision difficulties - this application provides support for users with vision difficulties (vision impairment) - tries to respect Windows skins and color schemas.

Marxio FCV is a clean software. It does not contain any adverts. It does not integrate with Windows (unless user requested) and does not install any additional software nor it has spying mechanisms.

If you haven't found the function in this tool you looked for, I can develop it.

Note,
Marxio FCV target is to quickly calculate and verify ONE file and one checksum, not more. It's not any limit but this application works this way. Other application is being developed for calculating more files.

Tool Updated: CheckSum Fixer

Sat, 29 Dec 2007 01:15:23 GMT

Listed in categories: Executable CRC Calculators

Most recent version:
1.0

Most recent release date:
January 5, 2006

Description:
The PE files headers include a CheckSum field which is located into the
IMAGE_NT_HEADER->IMAGE_OPTIONAL_HEADER->CheckSum

This value is an overall checksum of the whole file, often not set and left to 0x0000 by most compilers and thus doesn't happens often to worry about it, but sometimes this value is used to check if there have been alterations in the executable file.
There is for example an API, MapFileAndCheckSum(), which calculates the real checksum of a PE file and reports also the value stored into the PE Header. It is then simple for simple protectors to detect alterations of a PE file, even of a single byte.

It's a simple technique that advanced protector doesn't use too often and you can of course intercept this API and modify it online or skip its call, but for example with PocketPC smartphones or system drivers this check is done by the operative system, so you simply have no choice to intercept this check and the only way is to fix the value stored in the PE file header.

This program simply does this conveniently. Already other tools have this functionality (LordPE for example), but I just wanted a fast program able to fix this checksum in a click (e.g. with LordPE you have to do at least 5, 6 clicks).

It is very handy with ring0 drivers which test this checksum value!
