Get-RandomHex

Get-RandomHex.ps1 is a PowerShell function designed to generate cryptographically secure random hexadecimal strings. A typical use case is the generation of a 16-byte (128-bit) key, which aligns with the recommended minimum entropy for session IDs as per OWASP guidelines.

Features

• Generates random hexadecimal strings based on a specified bit length.
• Uses cryptographically secure random number generation.

Usage

To generate a hex string in PowerShell without a desired bit length generates a key with the default bit length of 256:

.\Get-RandomHex.ps1

To generate a hex string in PowerShell based on a desired bit length:

.\Get-RandomHex.ps1 -BitLength 128

Installation

1. Clone or download this repository.
2. Import the provided .ps1 script into your PowerShell session.
3. Run Get-RandomHex.ps1 script, optional with the desired bit length parameter.
