SYNOPSIS

11       singularity sign [sign options...] <image path>

DESCRIPTION

16       The sign command allows a user to create a cryptographic signature on
17       either a
18         single data object or a list of data objects within the same SIF
19       group. By
20         default without parameters, the command searches for the primary
21       partition and
22         creates a verification block that is then added to the SIF container
23       file.
