singularity verify

Verify cryptographic signatures attached to an image

Synopsis

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.

singularity verify [verify options...] <image path>

Examples

$ singularity verify container.sif

-a, --all              verify all non-signature partitions in a SIF
-g, --groupid uint32   group ID to be verified
-h, --help             help for verify
-j, --json             output json
-l, --local            only verify with local keys
-i, --sif-id uint32    descriptor ID to be verified (default system-partition)
