Annotation of 43BSDReno/kerberosIV/des/READ_ME, revision 1.1.1.1

1.1       root        1: This directory contains the sources for the DES encryption library and
                      2: test programs.  
                      3: 
                      4: Two precautions-- 
                      5: 
                      6: 1)  under US law, DES software and hardware may not be
                      7:        exported without license from the US Dept of Commerce.
                      8: 
                      9: 2)     The only way to get a significant speedup of the algorithm is to
                     10:        use considerably more space, traded against time. Dont play
                     11:        with the code -- there is a high probability you will either
                     12:        make it slower, or wrong, or both.  This implementation was
                     13:        optimized for the UVAX 2.  Other architectures could benefit from
                     14:        some "asm" tweaking.
                     15: 
                     16: 3)     If you do play with the code, make sure that the test program
                     17:        "verify" still yields the expected answers.  Otherwise, your
                     18:        ciphertext will not decrypt under a standard implementation, such
                     19:        as on the VLSI chips that have been certified.
