The generation process can be tailored by the requester. The following section describes how to use the STM32MP Key Generator from command line

To run it, launch the STM32MP_KeyGen_CLI.exe executableģ STM32MP Key Generator command line interface To install the STM32MP Key Generator tool for windows, you need to install the STM32CubeProgrammer. To install the STM32MP Key Generator tool, you need to install the STM32CubeProgrammer. The STM32MP Key Generator software is tested on Ubuntu 14.04 and 16.04 32-bit and 64-bit and should work on any distribution. This section describes the requirements and procedure to use the STM32MP Key Generator software. Since only uncompressed format is supported, this byte is removed. The first byte of the public key is used to indicate whether the public key is in compressed or uncompressed format. The cipher selection is done using the -prvkey-enc option.Ĭontains the SHA-256 hash of the public key in binary format.The SHA-256 hash is calculated based on the public key without any encoding format. The encryption could be done using the AES128CBC or AES256CBC ciphers.

The STM32MP Key Generator software generates three files:Ĭontains the generated ECC public key in PEM format.Ĭontains the encrypted ECC private key in PEM format.
