(Ruby) Load Certificate (.cer) and Private Key (.pvk) generated from makecert

See more Certificates Examples

Demonstrates how to load a certificate (.cer) and private key (.pvk) from the files produced by makecert, such as in the following command:

makecert -sv mycertificate.pvk -n "CN=My Simple Certificate" mycertificate.cer -sky Exchange

# First load the .cer file.
# The certificate file (.cer) contains only the certificate (does not include the private key)
cert = Chilkat::CkCert.new()
success = cert.LoadFromFile("qa_data/certs_and_keys/makecert/mycertificate.cer")
if (success == false)
    print cert.lastErrorText() + "\n";
    exit
end

# Next, load the .pvk file.
# Note: The password "secret" is what you entered when makecert displayed the dialog asking for a password..
privKey = Chilkat::CkPrivateKey.new()
success = privKey.LoadPvkFile("qa_data/certs_and_keys/makecert/mycertificate.pvk","secret")
if (success == false)
    print privKey.lastErrorText() + "\n";
    exit
end

# Finally, associate the private key with the certificate.
success = cert.SetPrivateKey(privKey)
if (success == false)
    print cert.lastErrorText() + "\n";
    exit
end

# At this point, the certificate can be used for signing.  For example..
pdf = Chilkat::CkPdf.new()

# ....
# ....

success = pdf.SetSigningCert(cert)

# ...
# ....

# Some Chilkat classes also provide a method where the cert and private key can be passed separately.
# For example, if SetSigningCert2 is called, then we don't need to explicitly associate the private key with the cert.
success = pdf.SetSigningCert2(cert,privKey)
