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"
68 Select this option if you want to use a PCI-attached cryptographic
70 + PCI Cryptographic Accelerator (PCICA)
71 + PCI Cryptographic Coprocessor (PCICC)
72 + PCI-X Cryptographic Coprocessor (PCIXCC)
73 + Crypto Express2 Coprocessor (CEX2C)
74 + Crypto Express2 Accelerator (CEX2A)
76 config ZCRYPT_MONOLITHIC
77 bool "Monolithic zcrypt module"
80 Select this option if you want to have a single module z90crypt.ko
81 that contains all parts of the crypto device driver (ap bus,
82 request router and all the card drivers).
84 config CRYPTO_SHA1_S390
85 tristate "SHA1 digest algorithm"
89 This is the s390 hardware accelerated implementation of the
90 SHA-1 secure hash standard (FIPS 180-1/DFIPS 180-2).
92 config CRYPTO_SHA256_S390
93 tristate "SHA256 digest algorithm"
97 This is the s390 hardware accelerated implementation of the
98 SHA256 secure hash standard (DFIPS 180-2).
100 This version of SHA implements a 256 bit hash with 128 bits of
101 security against collision attacks.
103 config CRYPTO_DES_S390
104 tristate "DES and Triple DES cipher algorithms"
107 select CRYPTO_BLKCIPHER
109 This us the s390 hardware accelerated implementation of the
110 DES cipher algorithm (FIPS 46-2), and Triple DES EDE (FIPS 46-3).
112 config CRYPTO_AES_S390
113 tristate "AES cipher algorithms"
116 select CRYPTO_BLKCIPHER
118 This is the s390 hardware accelerated implementation of the
119 AES cipher algorithms (FIPS-197). AES uses the Rijndael
122 Rijndael appears to be consistently a very good performer in
123 both hardware and software across a wide range of computing
124 environments regardless of its use in feedback or non-feedback
125 modes. Its key setup time is excellent, and its key agility is
126 good. Rijndael's very low memory requirements make it very well
127 suited for restricted-space environments, in which it also
128 demonstrates excellent performance. Rijndael's operations are
129 among the easiest to defend against power and timing attacks.
131 On s390 the System z9-109 currently only supports the key size
135 tristate "Pseudo random number generator device driver"
139 Select this option if you want to use the s390 pseudo random number
140 generator. The PRNG is part of the cryptographic processor functions
141 and uses triple-DES to generate secure random numbers like the
142 ANSI X9.17 standard. The PRNG is usable via the char device

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