# 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.
pem = chilkat2.Pem()

# Load the PEM from a file.
# If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
password = "myPassword"
success = pem.LoadPemFile("../myPemFiles/myPem.pem",password)
if (success != True):
    print(pem.LastErrorText)
    sys.exit()

# Note: If the app already has the PEM pre-loaded in a string variable, then load it 
# by calling LoadPem instead.  
pemContent = "... the PEM contents ..."
success = pem.LoadPem(pemContent,password)
# 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.
alias = "anything_I_want_here"

# This is the passord that will be required to access the created JKS.
jksPassword = "myJksSecret"
# jks is a CkJavaKeyStore
jks = pem.ToJks(alias,jksPassword)
if (pem.LastMethodSuccess == False):
    print(pem.LastErrorText)
    sys.exit()

# 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.  
success = jks.ToFile(jksPassword,"../myJksFiles/myJks.jks")
