PBKDF2 - Derive Key from Password

See more Encryption Examples

Demonstrates how to derive a symmetric encryption key from a password using PBKDF2. PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$crypt = New-Object Chilkat.Crypt2

$pw = "password"

$pwCharset = "utf-8"

# Such as sha256, sha512
$hashAlg = "sha256"

# 16 bytes
$saltHex = "78578E5A5D63CB0668AB39B21C8637FA"

$iterationCount = 100000

# Derive a 256-bit key from the password.
$outputBitLen = 256

# 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.)
$enc = "hex"

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

$($hexKey)

# Sample output:
