PowerShell Secret Generation

PowerShell Secret Generation refers to the use of shell-native primitives and profile-based functions to create strong, memorable, and low-dependency cryptographic secrets.

Core Philosophies

Offline First: Generation happens locally to reduce exposure to network-based threats.
Cryptographic Rigor: Preferring the .NET RandomNumberGenerator over standard pseudo-random helpers.
Ergonomic Strength: Favoring Passphrases (word-based) over Passwords (random character-based) for human-centric scenarios.

Implementation Patterns

1. Passphrases (Word-Based)

Passphrases rely on a strong local corpus (e.g., the EFF large word list).

Entropy: Derived from the number of words and the size of the corpus.
Example: dose-hazelnut-flounder-strategy-saddlebag-magician10

2. Character-Based (One-Liners)

Useful for quick, high-entropy secrets where memorability is not required.

Hex-Encoded Randomness:

-join([Security.Cryptography.RandomNumberGenerator]::GetBytes(18)|% ToString x2)

Custom Character Set:

$chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()-_+='
-join (1..20 | ForEach-Object { $chars[(Get-Random -Maximum $chars.Length)] })

Golfed One-Liner (Path Proxy):

[IO.Path]::GetRandomFileName()
