Cryptographic signature, verification, and encryption of images is
provided by host tools using OpenSSL's libcrypto. Select 'n' here if
you wish to build host tools without OpenSSL. mkimage will not have
the ability to sign images.

# A note on target vs host configuration:
#
# Host tools can be used across multiple targets, or different configurations
# of the same target. Thus, host tools must be able to handle any combination
# of target configurations. To prevent having different variations of the same
# tool, the tool build options may not depend on target configuration.
#
# Some linux distributions package these utilities as u-boot-tools, and it
# would be unmaintainable to have a different tool variation for each
# arch or configuration.
#
# A couple of simple rules:
#
# 1) Do not use target CONFIG_* options to enable or disable features in host
# tools. Only use the configs from tools/Kconfig
# 2) It's okay to use target configs to disable building specific tools.
# That's as long as the features of those tools aren't modified.
#
# Enable all the config-independent tools
