// 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

// Keys are exported in XML format:
lcPublicKeyXml = loRsa.ExportPublicKey()
? lcPublicKeyXml

lcPrivateKeyXml = loRsa.ExportPrivateKey()
? lcPrivateKeyXml

// Save the private key in PEM format:
loPrivKey = createobject("CkPrivateKey")
llSuccess = loPrivKey.LoadXml(lcPrivateKeyXml)
llSuccess = loPrivKey.SavePemFile("privateKey.pem")

// Save the public key in PEM format:
loPubKey = createobject("CkPublicKey")
llSuccess = loPubKey.LoadFromString(lcPublicKeyXml)
llSuccess = loPubKey.SavePemFile(.F.,"publicKey.pem")


release loRsa
release loPrivKey
release loPubKey
