$pw = "password"
$pwCharset = "ansi"
# Hash algorithms may be: sha1, md2, md5, etc.
$hashAlg = "sha1"
# The salt should be 8 bytes:
$saltHex = "78578E5A5D63CB06"
$iterationCount = 2048
# Derive a 192-bit key from the password.
$outputBitLen = 192

# The derived key is returned as a hex or base64 encoded string.
# (Note: The salt argument must be a string that also uses
# the same encoding.)

$hexKey = $crypt.Pbkdf2($pw,$pwCharset,$hashAlg,$saltHex,$iterationCount,$outputBitLen,$enc)

$($hexKey)

# The output should have this value:
