      \h|SYNOPSIS|

      \c{\b{openssl-client --help}\n
         \b{openssl-client --version}\n
         \b{openssl-client} rsautl [<options>]}

      \h|DESCRIPTION|

      The \cb{rsautl} command is a drop-in replacement for the
      \cb{openssl-rsautl(1)} cryptographic operations. Instead of performing
      the operations itself, it forwards the request to an OpenSSL key agent
      that keeps the private key unlocked for the session.

      Currently, data signing with a private key stored in a \cb{PKCS#11}
      token is the only supported arrangement. This limits the
      \cb{openssl-rsautl(1)} options and values to the following usage:

      \
      $ openssl-client rsautl -sign -keyform engine -engine pkcs11 -inkey pkcs11:...
      \

      This command reads data from \cb{stdin}, asks
      \cb{openssl-agent-pkcs11(1)} to sign it using the specified unlocked
      private key, and prints the resulting signature to \cb{stdout}.

      The command can be simulated without actually performing any
      cryptographic operations. If the \cb{--simulate} option is specified
      with the \cb{success} outcome, then the command prints a dummy signature
      produced by the agent and exits with zero status. The \cb{failure}
      outcome causes it to print the diagnostics to \cb{stderr} and exit with
      non-zero status. This mode is mostly useful for OpenSSL key agents
      testing.

    \h|ENVIRONMENT|

    If \cb{-engine} is \cb{pkcs11}, then the \cb{OPENSSL_AGENT_PKCS11_SOCK}
    environment variable should be set to the Unix-domain socket of the
    \cb{openssl-agent-pkcs11(1)} daemon.

    \h|EXIT STATUS|

    Non-zero exit status is returned in case of an error.
