Versions:
OpenHashTab 3.1.1, published by independent developer namazso, integrates cryptographic checksum verification directly into the Windows Explorer file-properties dialog, eliminating the need for separate hash utilities. As a lightweight shell extension, it appends a new tab to the right-click Properties window, where users can instantly view or compare MD5, SHA-1, SHA-256, SHA-512, CRC32, Blake2sp, and other algorithms for any selected file or folder. The tool’s primary purpose is to confirm file integrity after download, transfer, or backup; common use cases range from verifying Linux ISO images, game mods, or firmware packages to detecting inadvertent corruption or malicious tampering in archived projects. Drag-and-drop support, clipboard integration, and simultaneous multi-file hashing streamline workflows for IT administrators, software developers, and security-conscious consumers alike. Since its initial release, the open-source project has evolved through five public versions, each refining performance, algorithm coverage, and interface localization while maintaining a minimal memory footprint. The utility belongs to the File Integrity & Hash Verification category and operates transparently, requiring no background service or elevated privileges once installed. OpenHashTab is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
