Sign in-toto commands

This section covers commands that you use in SMCTL to manage signatures. These commands are: sign, verify signature, and remove signature. Use flags to specify command parameters.

注意

SHA3 digest signing and verification is not currently supported for RSA keys.

Sign

Sign commands begin with:

smctl sign in-toto <subcommand>

Subcommands

The sign command supports these subcommands:

1. Subcommands for managing signatures
