The RSA signature can be written here, and the data read from here is the message. The message padding must be checked by software. When writing the RSA signature, the signature is copied to 0x1000B900-RSA_bytesize, length RSA_bytesize. The engine determines the RSA byte-size by checking where the first word of the signature was written. | The RSA signature can be written here, and the data read from here is the message.
