[Opendnssec-user]DS Calculation

[=?us-ascii?B?wfXLtg==?=]

Hi all,
Is there someone knows how to calculate DS RR? I find the formula in rfc 4034, but get puzzled:

"
The digest is calculated by concatenating the canonical form of the
   fully qualified owner name of the DNSKEY RR with the DNSKEY RDATA,
   and then applying the digest algorithm.

     digest = digest_algorithm( DNSKEY owner name | DNSKEY RDATA);

      "|" denotes concatenation

     DNSKEY RDATA = Flags | Protocol | Algorithm | Public Key.
"
If there is a DNSKEY RR as follows:
se.                     3600    IN      DNSKEY  257 3 5 AwEAAZYYG1hpk8XKHNHpdO/E

How to calculate ds using the formula above?
Is "1(se.|257|3|5|AwEAAZYYG1hpk8XK...)" right for sha-1 ? But I know it's wrong.
I have tried many other forms but haven't get the right result yet, is there anyone 
knows how to do it?

Best regards,
Stuart
