(Ruby) Transition from Crypt2.GetSignerCertChain to Crypt2.LastSignerCert

Provides instructions for replacing deprecated GetSignerCertChain method calls with LastSignerCert.

Note: This example requires Chilkat v11.0.0 or greater.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

crypt2 = Chilkat::CkCrypt2.new()

# ...
# ...
index = 0

# ------------------------------------------------------------------------
# The GetSignerCertChain method is deprecated:

# certchainObj is a CkCertChain
certchainObj = crypt2.GetSignerCertChain(index)
if (crypt2.get_LastMethodSuccess() == false)
    print crypt2.lastErrorText() + "\n";
    exit
end

# ...
# ...

# ------------------------------------------------------------------------
# Do the equivalent using LastSignerCert, and then get the certificate chain from the cert.
# Your application creates a new, empty Cert object which is passed 
# in the last argument and filled upon success.

signerCert = Chilkat::CkCert.new()
success = crypt2.LastSignerCert(index,signerCert)
if (success == false)
    print crypt2.lastErrorText() + "\n";
    exit
end

certChain = Chilkat::CkCertChain.new()
success = signerCert.BuildCertChain(certChain)
if (success == false)
    print signerCert.lastErrorText() + "\n";
    exit
end
