We can't export DES code from the United - * States to other countries (even though the code already exists - * outside the U.S. -- go figure that one out) but we need to make - * Secure RPC work. The normal way around this is to break the DES - * code out into a shared library; we can then provide a dummy lib - * in the base OS and provide the real lib in the secure dist, which - * the user can install later. But we need Secure RPC for NIS+, and - * there are several system programs that use NIS+ which are statically - * linked. We would have to provide replacements for these programs - * in the secure dist, but there are a lot, and this is a pain. The - * shared lib trick won't work for these programs, and we can't change - * them once they're compiled. - * - * One solution for this problem is to do the DES encryption as a system - * call; no programs need to be changed and we can even supply the DES - * support as an LKM. But this bloats the kernel. Maybe if we have - * Secure NFS one day this will be worth it, but for now we should keep - * this mess in user space. - * - * So we have this second solution: we provide a server that does the - * DES encryption for us. In this case, the server is keyserv (we need - * it to make Secure RPC work anyway) and we use this protocol to ship - * the data back and forth between keyserv and the application. - */ - -enum des_dir { ENCRYPT_DES, DECRYPT_DES }; -enum des_mode { CBC_DES, ECB_DES }; - -struct desargs { - u_char des_key[8]; /* key (with low bit parity) */ - des_dir des_dir; /* direction */ - des_mode des_mode; /* mode */ - u_char des_ivec[8]; /* input vector */ - opaque desbuf<>; -}; - -struct desresp { - opaque desbuf<>; - u_char des_ivec[8]; - int stat; -}; - -program CRYPT_PROG { - version CRYPT_VERS { - desresp - DES_CRYPT(desargs) = 1; - } = 1; -} = 600100029; |
