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

loRsa = createobject("CkRsa")

// Generate a 1024-bit key.  Chilkat RSA supports
// key sizes ranging from 512 bits to 4096 bits.
llSuccess = loRsa.GenerateKey(1024)
if (llSuccess <> .T.) then
    ? loRsa.LastErrorText
    release loRsa
    return
endif

// Get the private key as unencrypted XML:
lcKeyXml = loRsa.ExportPrivateKey()
? lcKeyXml

// 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:
loPrivKey = createobject("CkPrivateKey")

llSuccess = loPrivKey.LoadXml(lcKeyXml)
if (llSuccess <> .T.) then
    ? loPrivKey.LastErrorText
    release loRsa
    release loPrivKey
    return
endif

lcStrEncPem = loPrivKey.GetPkcs8EncryptedPem("myPassword")

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


release loRsa
release loPrivKey
