NAME         top

     ssh-pkcs11-helper — ssh-agent helper program for PKCS#11 support

SYNOPSIS         top

     ssh-pkcs11-helper [-v]

DESCRIPTION         top

     ssh-pkcs11-helper is used by ssh-agent(1) to access keys provided by a
     PKCS#11 token.

     ssh-pkcs11-helper is not intended to be invoked by the user, but from

     A single option is supported:

     -v      Verbose mode.  Causes ssh-pkcs11-helper to print debugging mes‐
             sages about its progress.  This is helpful in debugging prob‐
             lems.  Multiple -v options increase the verbosity.  The maximum
             is 3.

             Note that ssh-agent(1) will automatically pass the -v flag to
             ssh-pkcs11-helper when it has itself been placed in debug mode.
