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.

29 select CRYPTO_BLKCIPHER
32 Use VIA PadLock for AES algorithm.

36 If unsure say M. The compiled module will be
39 config CRYPTO_DEV_PADLOCK_SHA
40 tristate "PadLock driver for SHA1 and SHA256 algorithms"
41 depends on CRYPTO_DEV_PADLOCK
45 Use VIA PadLock for SHA1/SHA256 algorithms.

52 config CRYPTO_DEV_GEODE
53 tristate "Support for the Geode LX AES engine"
54 depends on X86_32 && PCI
56 select CRYPTO_BLKCIPHER
58 Say 'Y' here to use the AMD Geode LX processor on-board AES
59 engine for the CryptoAPI AES algorithm.
61 To compile this driver as a module, choose M here: the module
62 will be called geode-aes.

79 bool "Monolithic zcrypt module"
82 Select this option if you want to have a single module z90crypt.ko
83 that contains all parts of the crypto device driver (ap bus,
84 request router and all the card drivers).
86 config CRYPTO_SHA1_S390
87 tristate "SHA1 digest algorithm"
91 This is the s390 hardware accelerated implementation of the
92 SHA-1 secure hash standard (FIPS 180-1/DFIPS 180-2).
94 config CRYPTO_SHA256_S390
95 tristate "SHA256 digest algorithm"
99 This is the s390 hardware accelerated implementation of the
100 SHA256 secure hash standard (DFIPS 180-2).
102 This version of SHA implements a 256 bit hash with 128 bits of
103 security against collision attacks.
105 config CRYPTO_SHA512_S390
106 tristate "SHA384 and SHA512 digest algorithm"
110 This is the s390 hardware accelerated implementation of the
111 SHA512 secure hash standard.
113 This version of SHA implements a 512 bit hash with 256 bits of
114 security against collision attacks. The code also includes SHA-384,
115 a 384 bit hash with 192 bits of security against collision attacks.
118 config CRYPTO_DES_S390
119 tristate "DES and Triple DES cipher algorithms"
122 select CRYPTO_BLKCIPHER
124 This us the s390 hardware accelerated implementation of the
125 DES cipher algorithm (FIPS 46-2), and Triple DES EDE (FIPS 46-3).

128 tristate "AES cipher algorithms"
131 select CRYPTO_BLKCIPHER
133 This is the s390 hardware accelerated implementation of the
134 AES cipher algorithms (FIPS-197). AES uses the Rijndael
137 Rijndael appears to be consistently a very good performer in
138 both hardware and software across a wide range of computing
139 environments regardless of its use in feedback or non-feedback
140 modes. Its key setup time is excellent, and its key agility is
141 good. Rijndael's very low memory requirements make it very well
142 suited for restricted-space environments, in which it also
143 demonstrates excellent performance. Rijndael's operations are
144 among the easiest to defend against power and timing attacks.
146 On s390 the System z9-109 currently only supports the key size
150 tristate "Pseudo random number generator device driver"
154 Select this option if you want to use the s390 pseudo random number
155 generator. The PRNG is part of the cryptographic processor functions
156 and uses triple-DES to generate secure random numbers like the
157 ANSI X9.17 standard. The PRNG is usable via the char device
