Author: delphij Date: Mon Aug 20 18:26:16 2012 New Revision: 239459 URL: http://svn.freebsd.org/changeset/base/239459 Log: MFC r239169: RFC 2289 requires all hashes be stored in little endian format before folding to 64 bits, while SHA1 code is big endian. Therefore, a bswap32 is required before using the value. Without this change, the implementation does not conform to test vector found in RFC 2289.
