Convert to DER encoded X.509 Certificate (.cer, .crt)

See more Certificates Examples

Loads a digital certificate from any format and saves to a binary DER encoded X.509 Certificate (.cer, .crt). Ruby

require 'chilkat'

success = false

cert = Chilkat::CkCert.new()

# LoadFromFile will load virtually any certificate format file.
# It will auto-recognize the format and load appropiately.
# In this case, load a PEM format certificate and convert to DER.
success = cert.LoadFromFile("/Users/chilkat/testData/pem/chilkat.pem")
if (success != true)
    print cert.lastErrorText() + "\n";
    exit
end

success = cert.ExportCertDerFile("chilkat.der")
if (success != true)
    print cert.lastErrorText() + "\n";
    exit
end

print "Converted certificate from PEM to DER format." + "\n";
