    The SEGGER encryption library has specialized hardware-assisted ciphering support

    There are two variants of the CRYP processor with different capabilities present on the following family members:

    • STM32F41x CRYP, hereafter referred to as the standard CRYP processor, and
    • STM32F43x/F47x CRYP, hereafter referred to as the enhanced CRYP processor.

    The following cryptographic algorithms using using both CRYP variants:

    • DES in ECB and CBC modes.
    • TDES in ECB and CBC modes with keying options 1, 2, and 3.
    • AES-128, AES-192, and AES-256 in ECB and CBC modes.

    For the enhanced CRYP processor, direct acceleration is provided for:

    • STM32F75x
    • STM32H75x
    • AES-128, AES-192, and AES-256 in CCM(12,4) and GCM(12,4) modes.

    For the standard CRYP processor, acceleration is provided for:

    • AES-128, AES-192, and AES-256 ciphering with GCM and CCM in software.
