PowerBuilder example code showing how to generate an RSA public/private key pair and export to PEM files.

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

loo_Rsa = create oleobject
// Use "Chilkat_9_5_0.Rsa" for versions of Chilkat < 10.0.0
li_rc = loo_Rsa.ConnectToNewObject("Chilkat.Rsa")
if li_rc < 0 then
    destroy loo_Rsa
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// Generate a 1024-bit key.  Chilkat RSA supports
// key sizes ranging from 512 bits to 4096 bits.
li_Success = loo_Rsa.GenerateKey(1024)
if li_Success <> 1 then
    Write-Debug loo_Rsa.LastErrorText
    destroy loo_Rsa

end if

// Keys are exported in XML format:
ls_PublicKeyXml = loo_Rsa.ExportPublicKey()
Write-Debug ls_PublicKeyXml

ls_PrivateKeyXml = loo_Rsa.ExportPrivateKey()
Write-Debug ls_PrivateKeyXml

// Save the private key in PEM format:
loo_PrivKey = create oleobject
// Use "Chilkat_9_5_0.PrivateKey" for versions of Chilkat < 10.0.0
li_rc = loo_PrivKey.ConnectToNewObject("Chilkat.PrivateKey")

li_Success = loo_PrivKey.LoadXml(ls_PrivateKeyXml)
li_Success = loo_PrivKey.SavePemFile("privateKey.pem")

// Save the public key in PEM format:
loo_PubKey = create oleobject
// Use "Chilkat_9_5_0.PublicKey" for versions of Chilkat < 10.0.0
li_rc = loo_PubKey.ConnectToNewObject("Chilkat.PublicKey")

li_Success = loo_PubKey.LoadFromString(ls_PublicKeyXml)
