Usage Information
This command verifies the signature of the OS10 image file using hash-based authentication, GNU privacy guard (Gn uPG or GPG)-based signatures, or digital signatures (PKI-signed). For GPG validation, before you validate the OS10 image, use the image gpg-key command to install the GPG key in the switch keyring.
