Versions:
HashCheck Shell Extension 2.5.0.1 by idrassi is a context-menu add-on that integrates hash verification directly into Windows Explorer, allowing users to check file integrity without launching a separate utility. After installation, a “Checksums” tab appears in every file or folder’s Properties dialog, where CRC-32, MD5, SHA-1, SHA-2 (256/384/512), and the new SHA3-256/384/512 algorithms can be computed or verified in a single pass. Multithreading support introduced in this release leverages all available CPU cores, cutting calculation time on large ISO, VHD, or backup archives by up to 70 %. A compact checksum file (.sfv, .md5, .sha1, .sha256, .sha384, .sha512, or the emerging .sha3) can be created alongside the source data; double-clicking any such file later re-opens the tab, automatically compares stored against freshly computed hashes, and highlights mismatches in red, providing an immediate pass/fail audit for downloads, ripped discs, or cloud-synced folders. The extension is frequently used by system administrators to validate deployment packages, by gamers to confirm scene releases, and by photographers to ensure memory-card dumps remain bit-perfect before re-formatting. Advanced options let users choose uppercase or lowercase output, prepend relative paths for portability, or switch between ANSI and UTF-8 encoding when saving checksum files. Because it lives only in the shell, the tool consumes no background resources and uninstalls cleanly through “Programs and Features.” HashCheck Shell Extension 2.5.0.1 is the first and currently only version offered under the idrassi label, superseding the original open-source project last updated in 2009. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
