Free checksum verifier software for windows

XCSV is an small useful program created to verify the integrity of files by using previously generated checksum files XCSV is an small useful program created to verify the integrity of files by using previously generated checksum files. The supported algorithms include CRC32 (Cyclic Redundancy Code), MD5 (Message Digest number 5) and SHA-1 (Secure Hash Algorithm).
The supported checksum files formats include SFV (Simple File Verification), MD5SUM and BSD-style, or "alternative" format.
XCSV is very simple utility and, for this reason, does not demand any installation utility. Simply unzip all files to any folder and run the executable file (usually, "xcsv.exe").
After starting the program, on the screen should appear the main program window. Click on the small button at right side of "Checksum file" edit field, and select the checksum file. Program will load the contents of checksum file into memory and show it on the list box field. The lines recognized as valid checksum values for appropriated files will be marked with small blue box, the format sign and the algorithm sign.
Then click on "Start" button for starting the checking of files. The files that have valid checksum will be marked with small green checkmark. The missing, corrupted or changed files will be marked with small red cross.
Currently, XCSV dont support any command line parameters except the name of checksum file to processing. If you prefer to work with command line, you always can use the original MD5 utility, or other *-nix style utilites.

Web Placement Verifier is a freeware application that will allow you to check your website search engine placement for multiple keywords, to see if your site is in the first top pages of a search engine result for a specific keyword search. Its important to be in the first top pages of a search result because most people using search engines dont go past the 3rd page.
Web Placement Verifier will search for the keywords entered and if it finds your site within the page depth selected, it will report the page number and position where it was found. You can try different keyword combinations, and also search for your competitors rankings. The tool is designed with a user-friendly interface and is easy to use.

Proxy Verifier - is a small and pretty fast proxy verifier developed in Visual Basic.
Just Add the url to which your proxy will be validated by clicking "Add URL" button, load your proxy list and hit "Start" and it will validate your proxy to that perticular URL which u want to check the proxy.

The Checksum Transformation will compute a hash value, the checksum, across one or more columns, returning the result in the Checksum output column.
The transformation provides functionality similar to the T-SQL CHECKSUM function, but is encapsulated within SQL Server Integration Services, for use within the pipeline without code or a SQL Server connection.
All input columns are passed through the transformation unaltered, those selected are used to generate the checksum which is passed out through a single output column, Checksum.
This does not restrict the number of columns available downstream from the transformation, as columns will always flow through a transformation. The Checksum output column is in addition to all existing columns within the pipeline buffer.
The Checksum Transformation does not support the following Integration Services data types, DT_NTEXT, DT_IMAGE and DT_BYTES.

File Checksum (Java) 3.0 brings a feature-rich and trustworthy Java 1.4 application to compute common checksums for files: CRC32, MD5, and SHA1. Checksums are small hexadecimal "signatures" for testing whether or not files have been copied correctly, such as over a network. One person sends a file along with the checksum computed on the original computer.

A second person calculates a similar checksum for the received file, and if the two checksums agree, then the received file is assumed to be correct. MD5 is more reliable than and preferred over the older and simpler CRC32. Many web sites provide MD5 signatures for their downloads; use this program to verify files that you download.
