/* For certain purposes we need a certificate id which has an upper
limit of the size. We use the hash of the issuer name and the
serial number for this. In most cases the serial number is not
that large and the resulting string can be passed on an assuan
command line. Everything is hexencoded with the serialnumber
delimted from the has by a dot.
The caller must free the string.
