# Script that can be used to generate CHIP device attestation certificates
# for testing purposes.
# The script expects the path to the chip-cert tool binary as an input argument.
#
# Usage example when the script is run from the CHIP SDK root directory:
# ./credentials/test/gen-test-attestation-certs.sh ./out/debug/standalone/chip-cert
#
# The result will be stored in:
# credentials/test/attestation
# If the intention is to re-generate a new set of attestation certificates that
# replace the already present ones then it is recommended to remove current certificates:
# rm credentials/test/attestation/*
#
# Second example also generates C-Style file with those certificates/keys to be use by the SDK tests:
# ./credentials/test/gen-test-attestation-certs.sh ./out/debug/standalone/chip-cert src/credentials/tests/CHIPAttCert_test_vectors
#
# In addition to the DER/PEM files this command also generates the following C-Style files:
# src/credentials/tests/CHIPAttCert_test_vectors.cpp
# src/credentials/tests/CHIPAttCert_test_vectors.h
#
