config CRYPTO_DEV_PADLOCK

	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.

	  Say 'Y' here to use the AMD Geode LX processor on-board AES
	  engine for the CryptoAPI AES algorithm.

	  To compile this driver as a module, choose M here: the module
	  will be called geode-aes.

	  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

config CRYPTO_SHA256_S390
	tristate "SHA256 digest algorithm"
	depends on S390
	select CRYPTO_ALGAPI
	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_DES_S390
	tristate "DES and Triple DES cipher algorithms"
	depends on S390
	select CRYPTO_ALGAPI

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.

	select CRYPTO_DES
	select CRYPTO_ALGAPI
