Literature: PowerShell Passphrase Generators

This note captures the research and design rationale for local passphrase and haiku-shaped secret generation using PowerShell 7.

Core Design Goals

  • Dependency Reduction: Improve local secret generation without large external tools.
  • Local Generation: Keep the process entirely within the user's shell environment.
  • Ergonomics: Create memorable yet strong secrets (passphrases vs. random strings).

Implemented Primitives

  • New-PPhrase: Generates random passphrases (e.g., word-word-word-12) using a local word list (EFF large list) and cryptographic randomness.
  • Add-PPhraseWord: A utility to curate a personal word corpus while maintaining lowercase normalization.
  • New-Haiku: A novel generator that synthesizes 5-7-5 syllable phrases, emitting both a poetic form and a hyphenated secret form.

Key Technical Lessons

  • Cryptographic Randomness: Use [Security.Cryptography.RandomNumberGenerator] instead of the standard Get-Random for secrets.
  • Corpus over Algorithm: Passphrase quality depends more on the size and selection method of the word source than on complex formatting.
  • Tool Boundary: The design explicitly avoids building a full "Password Manager" (which requires master keys, encryption, and history hygiene), focusing instead on "Secret Generation."

Synthesis

These utilities demonstrate the use of PowerShell Profile Functions as a lightweight way to embed secure workflows directly into the developer's daily environment.
