file hashing
About this tag
File hashing is a method used to verify file integrity and analyze malware samples. On Windows, users can create custom file hashing tools using PowerShell scripts and registry edits to add context menu entries for calculating MD5, SHA1, SHA256, and SHA512 hashes. This approach gives users full control over the hashing process and can be configured for computer-wide or per-user access. The technique is particularly useful for IT professionals and security analysts who frequently need to generate file hashes.
