menuconfig CRYPTO_HW
bool "Hardware crypto devices"
default y
---help---
Say Y here to get to see options for hardware crypto devices and
processors. This option alone does not add any kernel code.
If you say N, all options in this submenu will be skipped and disabled.
if CRYPTO_HW
config CRYPTO_DEV_PADLOCK
tristate "Support for VIA PadLock ACE"
depends on X86_32 && !UML
select CRYPTO_ALGAPI
help
Some VIA processors come with an integrated crypto engine
(so called VIA PadLock ACE, Advanced Cryptography Engine)
that provides instructions for very fast cryptographic
operations with supported algorithms.
The instructions are used only when the CPU supports them.
Otherwise software encryption is used.
config CRYPTO_DEV_PADLOCK_AES
tristate "PadLock driver for AES algorithm"
depends on CRYPTO_DEV_PADLOCK
select CRYPTO_BLKCIPHER
help
Use VIA PadLock for AES algorithm.
Available in VIA C3 and newer CPUs.
If unsure say M. The compiled module will be
called padlock-aes.ko
config CRYPTO_DEV_PADLOCK_SHA
tristate "PadLock driver for SHA1 and SHA256 algorithms"
depends on CRYPTO_DEV_PADLOCK
select CRYPTO_SHA1
select CRYPTO_SHA256
help
Use VIA PadLock for SHA1/SHA256 algorithms.
Available in VIA C7 and newer processors.
If unsure say M. The compiled module will be
called padlock-sha.ko
config CRYPTO_DEV_GEODE
tristate "Support for the Geode LX AES engine"
depends on X86_32 && PCI
select CRYPTO_ALGAPI
select CRYPTO_BLKCIPHER
help
Say 'Y' here to use the AMD Geode LX processor on-board AES
engine for the CryptoAPI AES algorithm.
To compile this driver as a module, choose M here: the module
will be called geode-aes.
config ZCRYPT
tristate "Support for PCI-attached cryptographic adapters"
depends on S390
select ZCRYPT_MONOLITHIC if ZCRYPT="y"
select HW_RANDOM
help
Select this option if you want to use a PCI-attached cryptographic
adapter like:
+ PCI Cryptographic Accelerator (PCICA)
+ PCI Cryptographic Coprocessor (PCICC)
+ PCI-X Cryptographic Coprocessor (PCIXCC)
+ Crypto Express2 Coprocessor (CEX2C)
+ Crypto Express2 Accelerator (CEX2A)
config ZCRYPT_MONOLITHIC
bool "Monolithic zcrypt module"
depends on ZCRYPT="m"
help
Select this option if you want to have a single module z90crypt.ko
that contains all parts of the crypto device driver (ap bus,
request router and all the card drivers).
config CRYPTO_SHA1_S390
tristate "SHA1 digest algorithm"
depends on S390
select CRYPTO_ALGAPI
help
This is the s390 hardware accelerated implementation of the
SHA-1 secure hash standard (FIPS 180-1/DFIPS 180-2).
config CRYPTO_SHA256_S390
tristate "SHA256 digest algorithm"
depends on S390
select CRYPTO_ALGAPI
help
This is the s390 hardware accelerated implementation of the
SHA256 secure hash standard (DFIPS 180-2).
This version of SHA implements a 256 bit hash with 128 bits of
security against collision attacks.
config CRYPTO_SHA512_S390
tristate "SHA512 digest algorithm"
depends on S390
select CRYPTO_ALGAPI
help
This is the s390 hardware accelerated implementation of the
SHA512 secure hash standard.
This version of SHA implements a 512 bit hash with 256 bits of
security against collision attacks.
config CRYPTO_DES_S390
tristate "DES and Triple DES cipher algorithms"
depends on S390
select CRYPTO_ALGAPI
select CRYPTO_BLKCIPHER
help
This us the s390 hardware accelerated implementation of the
DES cipher algorithm (FIPS 46-2), and Triple DES EDE (FIPS 46-3).
config CRYPTO_AES_S390
tristate "AES cipher algorithms"
depends on S390
select CRYPTO_ALGAPI
select CRYPTO_BLKCIPHER
help
This is the s390 hardware accelerated implementation of the
AES cipher algorithms (FIPS-197). AES uses the Rijndael
algorithm.
Rijndael appears to be consistently a very good performer in
both hardware and software across a wide range of computing
environments regardless of its use in feedback or non-feedback
modes. Its key setup time is excellent, and its key agility is
good. Rijndael's very low memory requirements make it very well
suited for restricted-space environments, in which it also
demonstrates excellent performance. Rijndael's operations are
among the easiest to defend against power and timing attacks.
On s390 the System z9-109 currently only supports the key size
of 128 bit.
config S390_PRNG
tristate "Pseudo random number generator device driver"
depends on S390
default "m"
help
Select this option if you want to use the s390 pseudo random number
generator. The PRNG is part of the cryptographic processor functions
and uses triple-DES to generate secure random numbers like the
ANSI X9.17 standard. The PRNG is usable via the char device
/dev/prandom.
config CRYPTO_DEV_HIFN_795X
tristate "Driver HIFN 795x crypto accelerator chips"
select CRYPTO_DES
select CRYPTO_ALGAPI
select CRYPTO_BLKCIPHER
select HW_RANDOM if CRYPTO_DEV_HIFN_795X_RNG
depends on PCI
help
This option allows you to have support for HIFN 795x crypto adapters.
config CRYPTO_DEV_HIFN_795X_RNG
bool "HIFN 795x random number generator"

help
Select this option if you want to enable the random number generator
on the HIFN 795x crypto adapters.
