.SYNOPSIS Calculates the SHA256 hash of a string. .DESCRIPTION The Get-Sha256 function calculates the SHA256 hash of a string. .PARAMETER string The string to hash. This is a mandatory parameter. .EXAMPLE Get-Sha256 -string "your-string" This example calculates the SHA256 hash of a string. .NOTES The function creates a new SHA256CryptoServiceProvider object, converts the string to a byte array using UTF8 encoding, computes the SHA256 hash of the byte array, converts the hash to a string and removes any hyphens, and returns the resulting hash. #> # This function calculates the SHA256 hash of a string. function Get-Sha256 ($string) { # Create a new SHA256CryptoServiceProvider object. $sha256 = New-Object System.Security.Cryptography.SHA256CryptoServiceProvider # Convert the string to a byte array using UTF8 encoding. $bytes = [System.Text.Encoding]::UTF8.GetBytes($string) # Compute the SHA256 hash of the byte array. $hash = $sha256.ComputeHash($bytes) # Convert the hash to a string and remove any hyphens. $result = [System.BitConverter]::ToString($hash) -replace '-' # Return the resulting hash. return $result } |
