require 'chilkat'

cert = Chilkat::CkCert.new()

#  Load from the PFX file
pfxFilename = "/Users/chilkat/testData/pfx/chilkat_ssl_pwd_is_test.pfx"
pfxPassword = "test"

#  A PFX typically contains certificates in the chain of authentication.
#  The Chilkat cert object will choose the certificate w/
#  private key farthest from the root authority cert.
#  To access all the certificates in a PFX, use the
#  Chilkat certificate store object instead.
success = cert.LoadPfxFile(pfxFilename,pfxPassword)
if (success != true)
    print cert.lastErrorText() + "\n";
    exit
end

#  Get some information about the digital certificate,
#  then get the private key...

#  DN = "Distinguished Name"
print "SubjectDN:" + cert.subjectDN() + "\n";

print "Common Name:" + cert.subjectCN() + "\n";
print "Issuer Common Name:" + cert.issuerCN() + "\n";

print "Serial Number:" + cert.serialNumber() + "\n";

#  Now for the private key...

# privKey is a CkPrivateKey
privKey = cert.ExportPrivateKey()
if (privKey == nil )
    print cert.lastErrorText() + "\n";
    exit
end

#  The private key object may be used in any Chilkat methods
#  (in other objects/classes) that expect a private key argument.

#  In this case, save the private key to a PKCS8 Encrypted PEM format file:
pemPassword = "secret"
pemPath = "/Users/chilkat/testData/pem/chilkat_privKey.pem"
success = privKey.SavePkcs8EncryptedPemFile(pemPassword,pemPath)
if (success != true)
    print privKey.lastErrorText() + "\n";

    exit
end

print "Private key saved to PKCS8 Encrypted PEM..." + "\n";
