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

// The Chilkat PEM class was introduced in v9.5.0.49.  
// It requires the bundle to be unlocked, as shown above.
loPem = createobject("CkPem")

// Load the PEM from a file.
// If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
lcPassword = "myPassword"
llSuccess = loPem.LoadPemFile("../myPemFiles/myPem.pem",lcPassword)
if (llSuccess <> .T.) then
    ? loPem.LastErrorText
    release loPem
    return
endif

// Note: If the app already has the PEM pre-loaded in a string variable, then load it 
// by calling LoadPem instead.  
lcPemContent = "... the PEM contents ..."
llSuccess = loPem.LoadPem(lcPemContent,lcPassword)
// Check for success as before..

// Convert to a JavaKeyStore object.
// The alias, if a non-empty string, will be applied to the 1st private key or 
// certificate.  All other keys and/or certificates will be assigned an auto-generated
// alias.
lcAlias = "anything_I_want_here"

// This is the passord that will be required to access the created JKS.
lcJksPassword = "myJksSecret"
loJks = loPem.ToJks(lcAlias,lcJksPassword)
if (loPem.LastMethodSuccess = .F.) then
    ? loPem.LastErrorText
    release loPem
    return
endif

// Save the JKS to a file.  The password passed here is used for the keyed hash of the
// entire JKS file.  This may be different (if desired) than the password for individual private keys
// contained within the JKS.  
llSuccess = loJks.ToFile(lcJksPassword,"../myJksFiles/myJks.jks")
if (llSuccess <> .T.) then
