# David Bryson Thu, Mar 21, 2002 # Config.help descriptions for CryptoAPI digest functions 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. There are no restrictions on the use of the MD5 algorithm. The Crypto- API implementation of MD5 is released under the GPL. See also 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 . 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. There are no restrictions on the use of the SHA1 algorithm. The CryptoAPI implementation of SHA1 is released under the GPL.
