7-Zip will calculate the checksums and display them in a separate window. If you need to display a list of checksums for a file in 7-Zip, use the CRC SHA\* command in the popup menu. Hash value of Dir\File2.dat: AA45BCF0 Usage %HASH% will be replaced with a string representation of the calculated hash value, and %FILENAME% will be replaced with the "packed" file’s name.įor example, you can use the mask "Hash value of %FILENAME%: %HASH%" to produce the following text file: Hash value of File1.dat: 765F90AC In the text file generated, there will be a line for each "packed" file. Here "NAME" is the name of the algorithm, "ext" is the file extension for the pseudo-archive checksum file, and “mask" defines the structure of each line in the checksum file. Use the following format when specifying the parameters: NAME=ext:mask The algorithm list in this section is independent of the list in the Main section. The Create section defines algorithms that can be used to generate text files with checksums. So we recommend that you enable only the algorithms that you actually need. Important! Enabling the additional hashing algorithms will increase the total time required for calculating the checksums. Each "0" value means means that 7-Zip will not use the hashing algorithm, and each "1" value means that 7-Zip will use it. The Main section defines additional checksum algorithms. If you open the file, you will see something like this: WinCryptHashers.ini is a plain-text file that allows you to configure the plugin. If you do that, each time you launch 7-Zip, it will automatically find the WinCryptHashers plugin and use it when displaying checksums.

After that, copy WinCryptHashers.64.dll or WinCryptHashers.32.dll (depending on your 7-Zip edition) and WinCryptHashers.ini to that subfolder. To install the plugin into the 7-Zip installation folder, you need to create the "Codecs" subfolder.

WinCryptHashers.ini – the configuration file.

WinCryptHashers.32.dll – the 32-bit version of the plugin.

WinCryptHashers.64.dll – the 64-bit version of the plugin.

The WinCryptHashers distribution package is an ordinary Zip archive that contains the following four files: You can download the ViPNet CSP cryptographic provider from the official page at (the website currently has only the Russian version). You can also install the ViPNet CSP cryptographic provider to add support for the following hashing algorithms: Important! SHA-384 and SHA-512 may be unavailable in Windows XP unless the Service Packs have been installed. The plugin can add support for the following hashing algorithms: WinCryptHashers also enables 7-Zip to generate text files with checksums. The plugin enables 7-Zip to display the hash values produced by additional hashing algorithms like MD5. WinCryptHashers is a small plugin for the popular 7-Zip archiver.
