DirHash

DirHash is a command-line utility capable of calculating the MD5, SHA1, SHA256, SHA384 and SHA512 checksums of your files and directories in lexicographical order using OpenSSL.
It requires intermediate experience with console-based applications to be able to run it without stumbling upon syntax errors.

Portable hash calculator

It's not necessary to install this app, since it's all packed in just one .exe file that can be saved anywhere on the disk or stored on a portable device to deploy it on any PC when you're on the move. It doesn't generate new registry entries or create extra files on the disk.
Double-clicking the .exe opens a Command Prompt window with the help documentation. To use DirHash, you have to call its process from a console panel.

Calculate hashes for files and folders

The usage syntax is DirHash.exe DirectoryOrFilePath [HashAlgo] [-t ResultFileName] [-overwrite] [-quiet] [-nowait] [-hashnames] [-exclude pattern1] [-exclude pattern2], where "DirectoryOrFilePath" is responsible with the path to the file or folder you want to process. If they're in the same location as the app, then it's not necessary to set the path.

Save all checksums in a file

"HashAlgo" can be replaced with the hash algorithm you're interested in learning: MD5, SHA1, SHA256, SHA384 or SHA512. Moreover, you can specify the name of the file that will contain the alphanumerical values of all processed files ("-r ResultFileName").
You can also allow the utility to overwrite this file with new data if old one already exists ("-overwrite"), hide any error messages or other types of text besides the hashes from the output file ("-quiet"), avoid displaying the waiting prompt before exiting ("-nowait"), take file names into account when processing hashes ("-hashnames") as well as exclude any items from the task ("-exclude pattern1", "-exclude pattern2").

Speedy checksum calculator with command lines

All aspects considered, DirHash may not be accessible to the casual user with no previous experience in command-line utilities, but it offers a quick method for calculating different hash types of multiple files and folders at the same time, as well as for creating a list with the results.
