87 - A pkey base and API kernel module (pkey.ko) which offers the
88 infrastructure for the pkey handler kernel modules, the ioctl
89 and the sysfs API and the in-kernel API to the crypto cipher
90 implementations using protected key.

92 loaded when pckmo support (that is generation of protected keys
93 from clear key values) is available.

640 help
641 This sets the default maximum request size to perform AES requests
642 using software instead of the crypto engine. It can be changed by
643 setting the aes_sw_max_len parameter.
644
645 Small blocks are processed faster in software than hardware.
646 Considering the 256-bit ciphers, software is 2-3 times faster than
647 qce at 256-bytes, 30% faster at 512, and about even at 768-bytes.
648 With 128-bit keys, the break-even point would be around 1024-bytes.
649
650 The default is set a little lower, to 512 bytes, to balance the
651 cost in CPU usage. The minimum recommended setting is 16-bytes
652 (1 AES block), since AES-GCM will fail if you set it lower.
653 Setting this to zero will send all requests to the hardware.
654
655 Note that 192-bit keys are not supported by the hardware and are
656 always processed by the software fallback, and all DES requests
657 are done by the hardware.
