how to generate rsf from a cia?

RSF aren't from CIAs. They're there to tell how to rebuild a cia or w/e. Example:

BasicInfo:
  CompanyCode             : 00
  ProductCode             : CTR-M-BFMX-00
  ContentType             : Application # Application / SystemUpdate / Manual / Child / Trial

TitleInfo:
  UniqueId                : 0x01798
  Category                : AddOnContents # Application / SystemApplication / Applet / Firmware / Base / DlpChild / Demo / Contents / SystemContents / SharedContents / AddOnContents / Patch / AutoUpdateContents

Just use notepad or any text editor to edit and save as .rsf. It's that simple nothing special. You can grab an example from here, as a guideline, you can't generate these.
