MD5 digest
CONFIG_DIGEST_MD5
  If you answer yes to this option, the MD5(Message Digest 5) digest 
  will be compiled into your kernel.  MD5 is an improved version of MD4
  designed by Ron Rivest, it produces a 128-bit "hash value" from an in-
  put of arbitrary length.  The effective strength of MD5 is 80bits.
  There are no restrictions on the use of the MD5 algorithm.  The Crypto-
  API implementation of MD5 is released under the GPL.

  See also <http://www.faqs.org/rfcs/rfc1321.html>

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called digest-md5.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

SHA1 digest
CONFIG_DIGEST_SHA1
  If you answer yes to this option the SHA1(Secure Hash Algorithm 1) will
  be compiled into your kernel.  SHA1 was designed with NIST and the NSA
  for use with the Digital Signature Standard.  It produces a 160-bit 
  hash value from an input or arbitrary length.  The effective strength of
  SHA1 is 80bits.  There are no restrictions on the use of the SHA1 algorithm.
  The CryptoAPI implementation of SHA1 is released under the GPL.

  inserted in and removed from the running kernel whenever you want).
  The module will be called digest-sha1.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

RIPEMD160 digest
CONFIG_DIGEST_RIPEMD160
  If you answer yes to this option the RIPEMD-160(RACE Integrity Primitives Evaluation Message Digest algorithm with 160bit digests) will
  be compiled into your kernel.  RIPEMD160 was designed by Hans Dobbertin, Antoon Bosselaers, and Bart Preneel
  for use with the European Union's project RIPE.  It produces a 160-bit 
  hash value from an input or arbitrary length.  The effective strength of
  RIPEMD160 is 80bits.  There are no restrictions on the use of the RIPEMD160 algorithm.
  The CryptoAPI implementation of RIPEMD160 is released under the GPL.

  module, say M here and read <file:Documentation/modules.txt>.

SHA256 digest
CONFIG_DIGEST_SHA256
  If you answer yes to this option the SHA256(Secure Hash Algorithm , 256bits) will
  be compiled into your kernel.  SHA256 was designed with NIST and the NSA
  for use with the Digital Signature Standard and the Advanced Encryption Standard
  with 128bit keys.  It produces a 256-bit hash value from an input or arbitrary length.
  The effective strength of SHA256 is 128bits.  There are no restrictions on the use of the
  SHA256 algorithm.  The CryptoAPI implementation of SHA256 is released under the GPL.

SHA384 digest
CONFIG_DIGEST_SHA384
  If you answer yes to this option the SHA384(Secure Hash Algorithm , 384bits) will
  be compiled into your kernel.  SHA384 was designed with NIST and the NSA
  for use with the Digital Signature Standard and the Advanced Encryption Standard
  with 192bit keys.  It produces a 384-bit hash value from an input or arbitrary length.
  The effective strength of SHA384 is 192bits.  There are no restrictions on the use of the
  SHA384 algorithm.  The CryptoAPI implementation of SHA384 is released under the GPL.

SHA512 digest
CONFIG_DIGEST_SHA512
  If you answer yes to this option the SHA512(Secure Hash Algorithm , 512bits) will
  be compiled into your kernel.  SHA512 was designed with NIST and the NSA
  for use with the Digital Signature Standard and the Advanced Encryption Standard
  with 256bit keys.  It produces a 512-bit hash value from an input or arbitrary length.
  The effective strength of SHA512 is 256bits.  There are no restrictions on the use of the
  SHA512 algorithm.  The CryptoAPI implementation of SHA512 is released under the GPL.
