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.

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).
85 tristate "Support for OMAP SHA1/MD5 hw engine"
86 depends on ARCH_OMAP24XX && CRYPTO_SHA1 && CRYPTO_MD5
88 OMAP processors have SHA1/MD5 module accelerator. Select this if you
89 want to use the OMAP module for SHA1/MD5 algorithms.
91 config CRYPTO_SHA1_S390
92 tristate "SHA1 digest algorithm"
96 This is the s390 hardware accelerated implementation of the
97 SHA-1 secure hash standard (FIPS 180-1/DFIPS 180-2).
99 config CRYPTO_SHA256_S390
100 tristate "SHA256 digest algorithm"
104 This is the s390 hardware accelerated implementation of the
105 SHA256 secure hash standard (DFIPS 180-2).
107 This version of SHA implements a 256 bit hash with 128 bits of
108 security against collision attacks.
110 config CRYPTO_DES_S390
111 tristate "DES and Triple DES cipher algorithms"
114 select CRYPTO_BLKCIPHER
116 This us the s390 hardware accelerated implementation of the
117 DES cipher algorithm (FIPS 46-2), and Triple DES EDE (FIPS 46-3).
119 config CRYPTO_AES_S390
120 tristate "AES cipher algorithms"
123 select CRYPTO_BLKCIPHER
125 This is the s390 hardware accelerated implementation of the
126 AES cipher algorithms (FIPS-197). AES uses the Rijndael
129 Rijndael appears to be consistently a very good performer in
130 both hardware and software across a wide range of computing
131 environments regardless of its use in feedback or non-feedback
132 modes. Its key setup time is excellent, and its key agility is
133 good. Rijndael's very low memory requirements make it very well
134 suited for restricted-space environments, in which it also
135 demonstrates excellent performance. Rijndael's operations are
136 among the easiest to defend against power and timing attacks.
138 On s390 the System z9-109 currently only supports the key size
142 tristate "Pseudo random number generator device driver"
146 Select this option if you want to use the s390 pseudo random number
147 generator. The PRNG is part of the cryptographic processor functions
148 and uses triple-DES to generate secure random numbers like the
149 ANSI X9.17 standard. The PRNG is usable via the char device
