In PowerShell, you can convert a hash string to a byte array by using the System.Text.Encoding class. First, you need to convert the hash string to a byte array by calling the FromHex method on the System.Text.Encoding class. Here's an example:

$hashString = "68656C6C6F20776F726C64" # example hash string $byteArray = [System.Text.Encoding]::ASCII.FromHex($hashString)

In this example, the $byteArray variable will now contain the byte array corresponding to the hash string "68656C6C6F20776F726C64". You can then use this byte array for further processing or manipulation as needed.

What is a hash string in PowerShell?

In PowerShell, a hash string refers to a string of characters that represents the computed hash value of a given input data. Hashing is a common technique used in computer science to convert input data into a fixed-size string of characters, which is typically used for data integrity verification, password storage, and other security-related purposes. The hash value is unique to the input data, meaning that even a slight change in the input data would result in a completely different hash value.

How to convert a hash string to a byte array and back in PowerShell?

To convert a hash string to a byte array in PowerShell, you can use the following code:

$hashString = "your_hash_string" $byteArray = [System.Text.Encoding]::UTF8.GetBytes($hashString)

To convert a byte array back to a hash string in PowerShell, you can use the following code:

$hashString = [System.Text.Encoding]::UTF8.GetString($byteArray)

Just replace "your_hash_string" with the actual hash string you want to convert.

How to convert a hash string to a byte array in a specific encoding in PowerShell?

You can convert a hash string to a byte array in a specific encoding in PowerShell using the following code:

$hashString = "your_hash_string" $encoding = [System.Text.Encoding]::UTF8

Convert the hash string to a byte array in the specified encoding

$byteArray = $encoding.GetBytes($hashString)

Print the byte array

$byteArray

Replace "your_hash_string" with the actual hash string that you want to convert. You can also change the encoding by replacing [System.Text.Encoding]::UTF8 with a different encoding, such as [System.Text.Encoding]::ASCII or [System.Text.Encoding]::UTF16.
