singularity sign¶

Attach a cryptographic signature to an image

Synopsis¶

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

To generate a keypair, see ‘singularity help key newpair’
