DirHash

When it comes to checking out the integrity of a file, you simply cannot go wrong with checking the digital signatures. If you are ever wary about a file that you downloaded from a more or less safe place, then you can put your mind at easy by verifying the hash value.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.

Considering that it is a console app, it requires intermediate experience with console-based applications to be able to run it without stumbling upon syntax errors. Providing you have some experience with this, you can get started by specifying the directory path of the file or folder to be processed.

"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").

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.
