The Problem: PowerShell’s Hashing Illusion

PowerShell, for all its flexibility, has a glaring gap: there is no clear, reliable way to hash complex objects deterministically. If you’ve ever tried to: ✅ Compare structured data ✅ Track changes over time ✅ Verify data integrity You’ve probably hit the same wall: Most hashing functions only work for files. Object hashing functions rely on non-deterministic serialization. There is no robust, structured way to hash deeply nested objects. Even worse, many common object hashing techniques in PowerShell produce false positives and false negatives without users realizing it.
