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 select CRYPTO_AES 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.

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_HASH 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_HASH 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 "SHA384 and SHA512 digest algorithm" depends on S390 select CRYPTO_HASH 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. The code also includes SHA-384, a 384 bit hash with 192 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" depends on CRYPTO_DEV_HIFN_795X help Select this option if you want to enable the random number generator on the HIFN 795x crypto adapters. config CRYPTO_DEV_TALITOS tristate "Talitos Freescale Security Engine (SEC)" select CRYPTO_ALGAPI select CRYPTO_AUTHENC select HW_RANDOM depends on FSL_SOC help Say 'Y' here to use the Freescale Security Engine (SEC) to offload cryptographic algorithm computation.
