singularity verify

Verify cryptographic signatures attached to an image


The verify command allows a user to verify cryptographic signatures on SIF container files. There may be multiple signatures for data objects and multiple data objects signed. By default the command searches for the primary partition signature. If found, a list of all verification blocks applied on the primary partition is gathered so that data integrity (hashing) and signature verification is done for all those blocks.
