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 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.
