  • STM32 crypto library package (X-CUBE-CRYPTOLIB) is based on STM32Cube architecture package and includes a set of crypto algorithms based on firmware implementation ready to use in all STM32 microcontrollers. This software is classified ECCN 5D002.

    For dedicated devices some algorithms are supported with hardware acceleration, to optimize the performance and the footprint usage.
    Up to 31 examples are provided in this package, covering all the available algorithms with template projects for the most common development tools, such as: Keil®MDK-ARM, IAR EWARM (IAR Embedded Workbench®), GCC-based IDEs (free AC6: SW4STM32, Atollic®TrueSTUDIO®,...). Even without the appropriate hardware evaluation board, this layer allows the user to quickly get started with a new STM32 cryptographic firmware library brand.
