Get-RandomHex.ps1

The latest version of Get-RandomHex.ps1, a PowerShell script designed to generate cryptographically secure random hexadecimal strings.

Features

  • Cryptographically Secure Random Number Generation: Utilizes the System.Security.Cryptography.RandomNumberGenerator class to ensure high entropy and security.
  • Customizable Bit Length: Generate hexadecimal strings of any specified bit length. Defaults to 256 bits if no length is specified.
  • Compatibility: Designed for compatibility with multiple .NET versions using RandomNumberGenerator.Create().
  • Ease of Use: Accepts the -BitLength parameter at both the script and function levels for flexibility.
  • Code-Signed with EV Certificate: This script is code-signed with an Extended Validation (EV) certificate to ensure authenticity and integrity.

Code Signing

The script is code-signed with an EV certificate to provide:

  • Authenticity: Verifies that the script originates from a trusted source.
  • Integrity: Ensures the code has not been altered since it was signed.

You can verify the code signature using the following PowerShell command:

Get-AuthenticodeSignature .\Get-RandomHex.ps1

Usage

Running the Script Directly

To generate a hex string without specifying a bit length (defaults to 256 bits):

.\Get-RandomHex.ps1

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

.\Get-RandomHex.ps1 -BitLength 128

Importing the Function into Your Session

You can import the function and use it directly in your PowerShell session:

# Import the function
. .\Get-RandomHex.ps1

# Generate a 256-bit random hexadecimal string
Get-RandomHexString

# Generate a 128-bit random hexadecimal string
Get-RandomHexString -BitLength 128

Installation

  1. Download the Get-RandomHex.ps1 script from this release.
  2. Verify the code signature to ensure the script's integrity.
  3. Run the script directly or import the function into your PowerShell session.

Example

Generate a 64-bit hexadecimal string:

.\Get-RandomHex.ps1 -BitLength 64
