Provides instructions for replacing deprecated GetSignedByCertChain 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'

email = Chilkat::CkEmail.new()

# ...

# ------------------------------------------------------------------------
# The GetSignedByCertChain method is deprecated:

# certChainObj is a CkCertChain
certChainObj = email.GetSignedByCertChain()
if (email.get_LastMethodSuccess() == false)
    print email.lastErrorText() + "\n";
    exit
end

# ...

# ------------------------------------------------------------------------
# Do the equivalent using LastSignerCert to get the signing certificate,
# then build the cert chain from the signing certificate object.

signerCert = Chilkat::CkCert.new()
success = email.LastSignerCert(0,signerCert)
if (success == false)
    print email.lastErrorText() + "\n";
    exit
end

# Get the certificate chain from the signer certificate.
certChain = Chilkat::CkCertChain.new()
success = signerCert.BuildCertChain(certChain)
if (success == false)
    print signerCert.lastErrorText() + "\n";
    exit
