Message-ID: <1350@daemen.UUCP> Date: Mon, 4-Nov-85 21:35:57 EST Article-I.D.: daemen.1350 Posted: Mon Nov 4 21:35:57 1985 Date-Received: Thu, 7-Nov-85 06:30:50 EST Distribution: net Organization: Daemen College, Buffalo, NY Lines: 41 Upon looking at the sources for crypt(1) I noticed the the undocumented -s (secure_flag). Does anyone no the exact purpose of this? Also there is a way to stop people from finding the password sent to crypt via ps(1), w(1), and sps(l). This is quite useful when using a shell script to encrypt a whole directory. Put in the following..... -------------------------------------------------------------------------------- main(argc, argv) char *argv[]; { register i, n1, n2, nr1, nr2; int secureflg = 0; if (argc > 1 && argv[1][0] == '-' && argv[1][1] == 's') { argc--; argv++; secureflg = 1; } if (argc != 2){ setup(getpass("Enter key:")); } else { setup(argv[1]); argv[1][0] = '\0'; ^^^^^^^^^^^^^^^^^^ } -- Doug Boyce Daemen College, Amherst NY UUCP : {decvax,dual,rocksanne,watmath,rocksvax}!sunybcs!daemen!boyce ihnp4!kitty!daemen!boyce ARPA : boyce@buffalo@csnet-relay "I order you to call your men back!"
