Final answer:
To view deleted keys in an Azure Key Vault using the Azure CLI, use the command 'az keyvault key list-deleted --vault-name YourKeyVaultName', replacing 'YourKeyVaultName' with the name of your own Key Vault.
Step-by-step explanation:
To show deleted keys in an Azure Key Vault using the Azure Command Line Interface (CLI), you would execute the following command:
az keyvault key list-deleted --vault-name YourKeyVaultName
This CLI command lists all keys that have been deleted from a specified Key Vault, where YourKeyVaultName is the name of your Azure Key Vault. The deleted keys can still be recovered or purged completely depending on the soft-delete setting and the retention period.
