[Fedora-packaging] Is md5sum compulsion in review instead sha1sum?

[Parag N(पराग़)]

Hi all,
   I want to know that is there really any compulsion on posting
md5sum instead sha1sum?  Review Guidelines said "Reviewers should use
md5sum for this task." I have started posting sha1sum for source in
package review.

Regards,
Parag.
