Usage: vault revoke [options] id

  Revoke a secret by its lease ID.

  This command revokes a secret by its lease ID that was returned
  with it. Once the key is revoked, it is no longer valid.

  With the -prefix flag, the revoke is done by prefix: any secret prefixed
  with the given partial ID is revoked. Lease IDs are structured in such
  a way to make revocation of prefixes useful.

General Options:

  -address=addr           The address of the Vault server.

  -ca-cert=path           Path to a PEM encoded CA cert file to use to
                          verify the Vault server SSL certificate.

  -ca-path=path           Path to a directory of PEM encoded CA cert files
                          to verify the Vault server SSL certificate. If both
                          -ca-cert and -ca-path are specified, -ca-path is used.

  -insecure               Do not verify TLS certificate. This is highly
                          not recommended. This is especially not recommended
                          for unsealing a vault.

Revoke Options:

  -prefix=true            Revoke all secrets with the matching prefix. This
                          defaults to false: an exact revocation.
