New Revision: 239169
URL: http://svn.freebsd.org/changeset/base/239169

Log:
  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.
