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; -- cgit v1.2.3
