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
Options
-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)
-u, --url string key server URL (default "https://keys.sylabs.io")
