- config CRYPTO_SHA1_S390
- tristate "SHA1 digest algorithm"
- depends on S390
- select CRYPTO_ALGAPI
- 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_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
- 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 cryptograhic 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.
