This directory contains some development keys to be used as the platform
root-of-trust key.
* arm_protprivk_rsa.pem is a 2K RSA private key in PEM format. It has been
generated using the openssl command line tool:
openssl genrsa 2048 > arm_protprivk_rsa.pem
* arm_protpk_rsa_sha256.bin is the SHA-256 hash of the DER-encoded public key
associated with the above private key. It has been generated using the openssl
command line tool:
openssl rsa -in arm_protprivk_rsa.pem -pubout -outform DER | \
openssl dgst -sha256 -binary > arm_protpk_rsa_sha256.bin
