The minimum recommended setting is 16-bytes 710 (1 AES block), since AES-GCM will fail if you set it lower. 711 Setting this to zero will send all requests to the hardware. 712 713 Note that 192-bit keys are not supported by the hardware and are 714 always processed by the software fallback, and all DES requests 715 are done by the hardware. 716 717config CRYPTO_DEV_QCOM_RNG 718 tristate "Qualcomm Random Number Generator Driver" 719 depends on ARCH_QCOM || COMPILE_TEST 720 select CRYPTO_RNG 721 help 722 This driver provides support for the Random Number 723 Generator hardware found on Qualcomm SoCs. 724 725 To compile this driver as a module, choose M here.
