Get the Certificate with Private Key from a Java KeyStore

See more Java KeyStore (JKS) Examples

Load a Chilkat certificate object from a Java KeyStore. Ruby

require 'chilkat'

success = false

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

#  Most of the time a .jks contains one certificate with it's associated private key.
#  (Similar to how a .pfx/.p12 usually contains a particular certificate with private key.)
#  This example demonstrates how to get the certificate with private key such that it can be used
#  by other Chilkat classes wherever a cert w/ private key is needed.
jks = Chilkat::CkJavaKeyStore.new()
password = "secret"
success = jks.LoadFile(password,"qa_data/jks/test_secret.jks")
if (success == false)
    print jks.lastErrorText() + "\n";
    exit
end

#  Make sure we have a private key.
if (jks.get_NumPrivateKeys() < 1)
    print "No private key available." + "\n";
    exit
end

#  -------------------------------------------------------------------------
#  Get the certificate chain associated with the 1st (and probably only) private key in the JKS.

chain = Chilkat::CkCertChain.new()
success = jks.CertChainAt(0,chain)
if (success == false)
    print jks.lastErrorText() + "\n";
    exit
end

cert = Chilkat::CkCert.new()
success = chain.CertAt(0,cert)
if (success == false)
    print chain.lastErrorText() + "\n";
    exit
end

#  Verify again that this cert has a private key.
if (cert.HasPrivateKey() != true)
    print "Certificate has no associated private key." + "\n";
    exit
end

#  We now have the cert object with it's associated private key, and it can be used in other Chilkat classes where needed.
#  For example..

crypt = Chilkat::CkCrypt2.new()
success = crypt.SetSigningCert(cert)
if (success == false)
    print crypt.lastErrorText() + "\n";
    exit
end
