3 bool "Hardware crypto devices"
6 Say Y here to get to see options for hardware crypto devices and
7 processors. This option alone does not add any kernel code.
9 If you say N, all options in this submenu will be skipped and disabled.
13 config CRYPTO_DEV_PADLOCK
14 tristate "Support for VIA PadLock ACE"
15 depends on X86_32 && !UML
18 Some VIA processors come with an integrated crypto engine
19 (so called VIA PadLock ACE, Advanced Cryptography Engine)
20 that provides instructions for very fast cryptographic
21 operations with supported algorithms.
23 The instructions are used only when the CPU supports them.
24 Otherwise software encryption is used.
26 config CRYPTO_DEV_PADLOCK_AES
27 tristate "PadLock driver for AES algorithm"
28 depends on CRYPTO_DEV_PADLOCK
29 select CRYPTO_BLKCIPHER
31 Use VIA PadLock for AES algorithm.
33 Available in VIA C3 and newer CPUs.
35 If unsure say M. The compiled module will be
38 config CRYPTO_DEV_PADLOCK_SHA
39 tristate "PadLock driver for SHA1 and SHA256 algorithms"
40 depends on CRYPTO_DEV_PADLOCK
44 Use VIA PadLock for SHA1/SHA256 algorithms.
46 Available in VIA C7 and newer processors.
48 If unsure say M. The compiled module will be
51 config CRYPTO_DEV_GEODE
52 tristate "Support for the Geode LX AES engine"
53 depends on X86_32 && PCI
55 select CRYPTO_BLKCIPHER
57 Say 'Y' here to use the AMD Geode LX processor on-board AES
58 engine for the CryptoAPI AES algorithm.
60 To compile this driver as a module, choose M here: the module
61 will be called geode-aes.
64 tristate "Support for PCI-attached cryptographic adapters"
66 select ZCRYPT_MONOLITHIC if ZCRYPT="y"
69 Select this option if you want to use a PCI-attached cryptographic
71 + PCI Cryptographic Accelerator (PCICA)
72 + PCI Cryptographic Coprocessor (PCICC)
73 + PCI-X Cryptographic Coprocessor (PCIXCC)
74 + Crypto Express2 Coprocessor (CEX2C)
75 + Crypto Express2 Accelerator (CEX2A)
77 config ZCRYPT_MONOLITHIC
78 bool "Monolithic zcrypt module"
81 Select this option if you want to have a single module z90crypt.ko
82 that contains all parts of the crypto device driver (ap bus,
83 request router and all the card drivers).
85 config CRYPTO_SHA1_S390
86 tristate "SHA1 digest algorithm"
90 This is the s390 hardware accelerated implementation of the
91 SHA-1 secure hash standard (FIPS 180-1/DFIPS 180-2).
93 config CRYPTO_SHA256_S390
94 tristate "SHA256 digest algorithm"
98 This is the s390 hardware accelerated implementation of the
99 SHA256 secure hash standard (DFIPS 180-2).
101 This version of SHA implements a 256 bit hash with 128 bits of
102 security against collision attacks.
104 config CRYPTO_DES_S390
105 tristate "DES and Triple DES cipher algorithms"
108 select CRYPTO_BLKCIPHER
110 This us the s390 hardware accelerated implementation of the
111 DES cipher algorithm (FIPS 46-2), and Triple DES EDE (FIPS 46-3).
113 config CRYPTO_AES_S390
114 tristate "AES cipher algorithms"
117 select CRYPTO_BLKCIPHER
119 This is the s390 hardware accelerated implementation of the
120 AES cipher algorithms (FIPS-197). AES uses the Rijndael
123 Rijndael appears to be consistently a very good performer in
124 both hardware and software across a wide range of computing
125 environments regardless of its use in feedback or non-feedback
126 modes. Its key setup time is excellent, and its key agility is
127 good. Rijndael's very low memory requirements make it very well
128 suited for restricted-space environments, in which it also
129 demonstrates excellent performance. Rijndael's operations are
130 among the easiest to defend against power and timing attacks.
132 On s390 the System z9-109 currently only supports the key size
136 tristate "Pseudo random number generator device driver"
140 Select this option if you want to use the s390 pseudo random number
141 generator. The PRNG is part of the cryptographic processor functions
142 and uses triple-DES to generate secure random numbers like the
143 ANSI X9.17 standard. The PRNG is usable via the char device

147 tristate "Driver HIFN 795x crypto accelerator chips"
150 select CRYPTO_BLKCIPHER
151 select HW_RANDOM if CRYPTO_DEV_HIFN_795X_RNG
154 This option allows you to have support for HIFN 795x crypto adapters.
