# 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.
# Quotes around eval are mandatory!
# 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.
