The directory containing the CoMID and CoRIM templates via the --template-dir switch (abbrev. -t). If this flag is not set the path for the template directory will default to templates within the current working directory. The template directory must exist and must contain files named comid-template.json and corim-template.json which contain the respective templates. Some examples of CoMID and CoRIM JSON templates can be found in the data/templates folder.
If you wish to specify the name and path of the produced endorsement then pass this via the corim-file switch (abbrev. -c). If this flag is not set then the produced endorsement will be saved in the current working directory under the file name psa-endorsements.cbor or cca-endorsements.cbor depending on the attestation scheme used.
