Binary Certificate Extension Data

See more Certificates Examples

Demonstrates how to binary certificate extension data by OID.

The GetExtensionBd method is added in Chilkat v9.5.0.96.

Ruby

require 'chilkat'

success = false

cert = Chilkat::CkCert.new()

success = cert.LoadFromFile("qa_data/certs/testCert.cer")
if (success == false)
    print cert.lastErrorText() + "\n";
    exit
end
