     ssh-pkcs11-helper — OpenSSH helper for PKCS#11 support

SYNOPSIS         top

     ssh-pkcs11-helper [-v]

DESCRIPTION         top

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

     ssh-pkcs11-helper is not intended to be invoked directly by the

     A single option is supported:

     -v      Verbose mode.  Causes ssh-pkcs11-helper to print debugging
             messages about its progress.  This is helpful in debugging
             problems.  Multiple -v options increase the verbosity.  The
             maximum is 3.

             Note that ssh(1), ssh-agent(1), and ssh-keygen(1) will
             automatically pass the -v flag to ssh-pkcs11-helper when
             they have themselves been placed in debug mode.
