Hi,
Can I consider issuerDN and serial number (both combined) of digital certificate unique for every certificate?

Is serial number of certificate different for every certificate issued by the same issuer?

Thanks,
Srini

The serial number is supposed to be unique as you suggest, according to RFC3280 section 4.1.2.2.
