Encrypt / Decrypt Secure Strings

See more Encryption Examples

Demonstrates how to use the EncryptSecureENC and DecryptSecureENC methods to encrypt/decrypt secure strings. These methods were added in Chilkat v9.5.0.71 (released January 2018). PowerShell

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

$success = $false

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

# Load the secure string with some text.
$secStr1 = New-Object Chilkat.SecureString
$success = $secStr1.LoadFile("qa_data/txt/helloWorld.txt","utf-8")
if ($success -ne $true) {
    $("Failed to load helloWorld.txt")
    exit
}

$crypt = New-Object Chilkat.Crypt2

$crypt.CryptAlgorithm = "aes"
$crypt.CipherMode = "cbc"
$crypt.KeyLength = 128
$crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex")
$crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex")
$crypt.EncodingMode = "base64"

# Return the base64 encoded encrypted contents of secStr1.
$encryptedStr = $crypt.EncryptSecureENC($secStr1)
$("Encrypted string: " + $encryptedStr)

# Output:
# Encrypted string: qiq+IFhcjTkEIkZyf31V/g==

# Decrypt to secStr2:
$secStr2 = New-Object Chilkat.SecureString
$crypt.DecryptSecureENC($encryptedStr,$secStr2)

# Access the contents of secStr2
$("Decrypted string: " + $secStr2.Access())

# Output:
# Decrypted string: Hello World!
