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