Hash is a small GUI tool designed to perform MD5, SHA1 and CRC32 hashing functions on a number of files. The file size and modified date is also optionally shown. Results displayed in the window can easily be copied to the Windows clipboard or saved to a text file.

The program allows direct browsing of multiple files and files can also be dragged and dropped onto the window. Files (with support for wildcard selections) can also be supplied on the command line.

A convenient use for this functionality is to place a shortcut to the program in the SendTo directory (C:\Documents and Settings\[name]\SendTo) so you can send arbitrary files to it from the Explorer shell.
