Security and Cryptography

Calculating a string's hash codes via .Net Cryptography

Utilizing .Net System.Security.Cryptography.HashAlgorithm namespace to generate the message hash code with the algorithms supported.

$example="Nobody expects the Spanish Inquisition."

#calculate
$hash=[System.Security.Cryptography.HashAlgorithm]::Create("sha256").ComputeHash(
[System.Text.Encoding]::UTF8.GetBytes($example))

#convert to hex
[System.BitConverter]::ToString($hash) 

#2E-DF-DA-DA-56-52-5B-12-90-FF-16-FB-17-44-CF-B4-82-DD-29-14-FF-BC-B6-49-79-0C-0E-58-9E-46-2D-3D

The "sha256" part was the hash algorithm used.

the - can be removed or change to lower case

#convert to lower case hex without '-' 
[System.BitConverter]::ToString($hash).Replace("-","").ToLower()

#2edfdada56525b1290ff16fb1744cfb482dd2914ffbcb649790c0e589e462d3d

If base64 format was preferred, using base64 converter for output

#convert to base64
[Convert]::ToBase64String($hash)
