(PowerShell) Hash the Contents of a String (SHA256 and other hash algorithms)

Demonstrates how to hash the contents of a string using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc.

# This example requires the Chilkat Crypt API to have been previously unlocked.
# See Unlock Chilkat Crypt for sample code.

$crypt = New-Object Chilkat.Crypt2

# Choose the hash algorithm.
# Can be  "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".
$crypt.HashAlgorithm = "sha256"

# The byte representation of the string matters when hashing. 
# Tell Chilkat that we want to use the utf-8 byte representation.
$crypt.Charset = "utf-8"

$hashBytes = $crypt.HashString("They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.")

# Let's examine the hash as a hex string.
$sb = New-Object Chilkat.StringBuilder
$sb.AppendEncoded($hashBytes,"hex")
