(PowerBuilder) Generate RSA Key and Export to Encrypted PEM

PowerBuilder sample showing how to generate an RSA key and export to encrypted PEM.

oleobject loo_Rsa
integer li_Success
string ls_KeyXml

// 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
    return
end if

// Get the private key as unencrypted XML:
ls_KeyXml = loo_Rsa.ExportPrivateKey()
Write-Debug ls_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:
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_KeyXml)
if li_Success <> 1 then
    Write-Debug loo_PrivKey.LastErrorText
    destroy loo_Rsa
    destroy loo_PrivKey
    return
end if

ls_StrEncPem = loo_PrivKey.GetPkcs8EncryptedPem("myPassword")

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