# 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
}

# Keys are exported in XML format:
$publicKeyXml = $rsa.ExportPublicKey()
$($publicKeyXml)

$privateKeyXml = $rsa.ExportPrivateKey()
$($privateKeyXml)

# Save the private key in PEM format:
$privKey = New-Object Chilkat.PrivateKey
$success = $privKey.LoadXml($privateKeyXml)
$success = $privKey.SavePemFile("privateKey.pem")

# Save the public key in PEM format:
$pubKey = New-Object Chilkat.PublicKey
$success = $pubKey.LoadFromString($publicKeyXml)
$success = $pubKey.SavePemFile($false,"publicKey.pem")
