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

loJks = CreateObject('Chilkat_9_5_0.JavaKeyStore')

lcJksPassword = "myJksPassword"
lcJksPath = "/someDir/keyStore.jks"

*  Load the Java keystore from a file.
lnSuccess = loJks.LoadFile(lcJksPassword,lcJksPath)
IF (lnSuccess <> 1) THEN
    ? loJks.LastErrorText
    RELEASE loJks
    CANCEL
ENDIF

*  A JKS private key entry consists of both the private key,
*  it's associated certificate (which contains the matching public key
*  within the X.509 of the certificate), and the certificates in the
*  chain of authentication to the root.
* 
*  Therefore, to add a private key entry to a JKS requires
*  a Chilkat certificate object that has a private key and which also
*  has the certificate chain (up to the root) available.

*  There are many ways to get a Chilkat certificate object
*  that contains (within it) the private key and the certificate chain
*  This example will show two possibilities:
*  (1) Where the cert and issuing root are provided in PEM format in .crt files,
*  and the private key is also provided in unencrypted PEM format (.key file).
*  (2) Where the cert, private key, and issuing root are provided in a single PFX.

*  First for the .crt / .key files:
loCert = CreateObject('Chilkat_9_5_0.Cert')

*  Chilkat will automatically determine the format of the cert file and load it correctly.
lnSuccess = loCert.LoadFromFile("/mycerts/alice.crt")
IF (lnSuccess <> 1) THEN
    ? loCert.LastErrorText
    RELEASE loJks
    RELEASE loCert
    CANCEL
ENDIF

*  Certificates required for building the chain of authentication can be
*  added to an XML certificate vault object, and then provided as
*  a source for obtaining certs when building the chain.
loCertVault = CreateObject('Chilkat_9_5_0.XmlCertVault')
lnSuccess = loCertVault.AddCertFile("/mycerts/ca.crt")
IF (lnSuccess <> 1) THEN
    ? loCertVault.LastErrorText
    RELEASE loJks
    RELEASE loCert
    RELEASE loCertVault
    CANCEL
ENDIF

lnSuccess = loCert.UseCertVault(loCertVault)
IF (lnSuccess <> 1) THEN
    ? loCert.LastErrorText
    RELEASE loJks
    RELEASE loCert
    RELEASE loCertVault
    CANCEL
ENDIF

*  Now provide the associated private key to the certificate object.
*  The Chilkat private key class provides methods for loading from many formats (both
*  encrypted and unencrypted).
loPrivKey = CreateObject('Chilkat_9_5_0.PrivateKey')
lnSuccess = loPrivKey.LoadPemFile("/mycerts/alice.key")
IF (lnSuccess <> 1) THEN
    ? loPrivKey.LastErrorText
    RELEASE loJks
    RELEASE loCert
    RELEASE loCertVault
    RELEASE loPrivKey
    CANCEL
ENDIF

*  Provide the certificate object with the private key:
lnSuccess = loCert.SetPrivateKey(loPrivKey)
IF (lnSuccess <> 1) THEN
    ? loCert.LastErrorText
    RELEASE loJks
    RELEASE loCert
    RELEASE loCertVault
    RELEASE loPrivKey
    CANCEL
ENDIF

*  Our certificate object now contains all that we need to add it as a private key entry
*  to the Java keystore:
lcAlias = "alice"
lnSuccess = loJks.AddPrivateKey(loCert,lcAlias,lcJksPassword)
IF (lnSuccess <> 1) THEN
    ? loJks.LastErrorText
    RELEASE loJks
    RELEASE loCert
    RELEASE loCertVault
    RELEASE loPrivKey
    CANCEL
ENDIF

*  Write the updated JKS, which contains the new private key entry w/ certificate chain.
lnSuccess = loJks.ToFile(lcJksPassword,lcJksPath)
IF (lnSuccess <> 1) THEN
    ? loJks.LastErrorText
    RELEASE loJks
    RELEASE loCert
    RELEASE loCertVault
    RELEASE loPrivKey
    CANCEL
ENDIF

? "Added new private key entry (from .crt and .key files) to the JKS!"

*  Now let's add a new private key entry from a PFX that contains a single
*  private key with associated cert and cert chain.
loPfx = CreateObject('Chilkat_9_5_0.Pfx')

lnSuccess = loPfx.LoadPfxFile("/myPfxFiles/my.pfx","pfxPassword")
IF (lnSuccess <> 1) THEN
    ? loPfx.LastErrorText
    RELEASE loJks
    RELEASE loCert
    RELEASE loCertVault
    RELEASE loPrivKey
    RELEASE loPfx
    CANCEL
ENDIF

*  This is easy -- simply add the PFX to the JKS
lcAlias = "bob"
lnSuccess = loJks.AddPfx(loPfx,lcAlias,lcJksPassword)
IF (lnSuccess <> 1) THEN
    ? loJks.LastErrorText
    RELEASE loJks
    RELEASE loCert
    RELEASE loCertVault
    RELEASE loPrivKey
    RELEASE loPfx
    CANCEL
ENDIF

*  Write the updated JKS, which contains the new private key entry w/ certificate chain
*  that came from the PFX.
lnSuccess = loJks.ToFile(lcJksPassword,lcJksPath)
IF (lnSuccess <> 1) THEN
    ? loJks.LastErrorText
    RELEASE loJks
    RELEASE loCert
    RELEASE loCertVault
    RELEASE loPrivKey
    RELEASE loPfx
    CANCEL
ENDIF

? "Added new private key entry (from PFX) to the JKS!"

RELEASE loJks
RELEASE loCert
RELEASE loCertVault
RELEASE loPrivKey
RELEASE loPfx
