Add-Type -Path "C:\chilkat\ChilkatDotNet47-9.5.0-x64\ChilkatDotNet47.dll"

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

$rsa = New-Object Chilkat.Rsa

# Generate a 1024-bit key.  Chilkat RSA supports
# key sizes ranging from 512 bits to 4096 bits.
$success = $rsa.GenerateKey(1024)
if ($success -ne $true) {
    $($rsa.LastErrorText)
    exit
}

# Get the private key as unencrypted XML:
$keyXml = $rsa.ExportPrivateKey()
$($keyXml)

# To encrypt the key -- meaning to get the key in
# an encrypted PEM format -- load it into a PrivateKey object,
# and then export to encrypted PEM:
$privKey = New-Object Chilkat.PrivateKey

$success = $privKey.LoadXml($keyXml)
if ($success -ne $true) {
    $($privKey.LastErrorText)
    exit
}

$strEncPem = $privKey.GetPkcs8EncryptedPem("myPassword")

# You now have the private key in an encrypted format,
# which may be (for example) saved to a database
