Support deleting signature #894
Description
Is your feature request related to a problem?
Currently, when users want to delete a signature from a signed image for some reasons, they have to use a third-party tool like ORAS to achieve it. We discussed in notaryproject/notaryproject.dev#248 and created a doc accordingly.
This process is not convenient for users because users have to install and use another tool. In general, deleting a Notary Project signature should be a fundamental capability of Notation.
What solution do you propose?
To help users conveniently delete the Notary Project signature, it would be good that Notation could support deleting a signature via a CLI command. The desired experience can be proposed in the CLI Spec if we agree this is a valid feature request.
What alternatives have you considered?
N/A
Any additional context?
