ssh-pkcs11-helper — ssh-agent helper program for PKCS#11 support
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 ssh-agent(1).
A single option is supported:
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-agent(1) will automatically pass the -v flag to ssh-pkcs11-helper when it has itself been placed in debug mode.
