Petr Menšík fa1631eef7 Simplify pkcs11 token generation
Make default secure enough, no predefined pins are used. Generate pin
and save it into file protected by unix rights. HSM tools will probably
require it anyway. Use smart defaults.

# This script will initialise token storage of softhsm PKCS11 provider
# in custom location. Is useful to store tokens in non-standard location.
#
# Output can be evaluated from bash, it will prepare it for usage of temporary tokens.
# Recommended use:
# eval $(bash setup-named-softhsm.sh -A)
#
SOFTHSM2_CONF="$1"
TOKENPATH="$2"
GROUPNAME="$3"
# Do not use this script for real keys worth protection
# This is intended for crypto accelerators using PKCS11 interface.
# Uninitialized token would fail any crypto operation.
