DirHash is a Windows console program that computes the hash of a given directory content or a single file. It also supports creating SUM of files in a way similar to classical shasum program. Recursive Lexicographical order is used for browsing the directory hierarchy so that the computed hash can be seen as unique fingerprint of the target directory. Supported hashing algorithms are MD5, SHA-1, SHA-256, SHA-384, SHA-512, Streebog, Blake2s, Blake2 and Blake3.

Usage

DirHash can be invoked from the command like as follows:
-

DirHash.exe DirectoryOrFilePath [HashAlgo] [-t ResultFileName] [-progress] [-sum] [-sumRelativePath] [-verify FileName] [-threads] [-clip] [-lowercase] [-overwrite] [-quiet] [-nologo] [-nowait] [-skipError] [-hashnames [-stripnames]] [-exclude pattern1] [-exclude patter2] [-nofollow]

DirHash can also use Windows native implementation for hash algorithms (using -mscrypto switch) which can enhance performance on some configuration especially ARM64.
