Dear friends of esteid-devel, I hope all your activities are fine.

After reading Libdigidocpp code I could see that certificate serial
number can be retrieved with function:

long digidoc::X509Cert::getSerial().

This function uses OpenSSL ASN1_INTEGER_get to return serial as long.
What do you think about getting certificate serial as hexadecimal or
decimal string using OpenSSL BIGNUM through ASN1_INTEGER_to_BN()?.
Once you get BIGNUM you could use the appropiate bn function in order
to get serial in hex or dec. This could avoid throwing an exception on
Libdigidocpp when it reads big serial numbers in some machines. It
could provide backward compatibility.

Best regards

Antonio
