* 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.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Pem')
loPem = CreateObject('Chilkat.Pem')

* Load the PEM from a file.
* If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
lcPassword = "myPassword"
lnSuccess = loPem.LoadPemFile("../myPemFiles/myPem.pem",lcPassword)
IF (lnSuccess <> 1) THEN
    ? loPem.LastErrorText
    RELEASE loPem
    CANCEL
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 ..."
lnSuccess = 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 = 0) THEN
    ? loPem.LastErrorText
    RELEASE loPem
    CANCEL
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.  
lnSuccess = loJks.ToFile(lcJksPassword,"../myJksFiles/myJks.jks")
IF (lnSuccess <> 1) THEN
    ? loJks.LastErrorText
    RELEASE loPem
    CANCEL
