-The change implemented here is that the operator password in irc.conf
-is no longer stored in plaintext form, but is encrypted the same way
-that user passwords are encrypted on normal UNIX systems. Ie, instead
-of having
-
-       O:*:goodboy:Nelson
-
-in your ircd.conf file, you have
-
-       O:*:sCnvYRmbFJ7oI:Nelson
-
-You still type "/oper Nelson goodboy" to become operator. However, if
-someone gets ahold of your ircd.conf file, they can no longer figure
-out what the password is from reading it.  There are still other
-security holes, namely server-server passwords, but this closes one
-obvious problem.
-
-So, how do you generate these icky looking strings for passwords?
-There's a simple program called mkpasswd to do that for you. To
-compile mkpasswd, just "make -f Makefile.crypt" in this directory. After it
-compiles, just run mkpasswd, and at the prompt type in your plaintext passwor\
-d.
-It will spit out the encrypted password, which you should then just copy
-into your ircd.conf file. This should be done only when adding new passwords
-to your ircd.conf file. Crypting of oper passwords is automatically done
-with the new F:lines so there is nothing to enable to be able to use
-crypted oper passwords. All you have to do is edit the Makefile.crypt in this
-directory and change "IRCDCONF = /usr/local/lib/irc/ircd.conf" to the full
-path to your ircd.conf file. Then "make -f Makefile.crypt install" in this
-directory to replace all the operator passwords in your ircd.conf file
-with the encrypted format.
-
-Choose your passwords carefully. Do not choose something in a
-dictionary, make sure its at least 5 characters. Anything past 8
-characters is ignored.
-
-One thing to note about crypt() passwords - for every plaintext, there
-are 4096 different passwords. Some valid encryptions of "goodboy"
-include t1Ub2RhRQHd4g sCnvYRmbFJ7oI and Xr4Z.Kg5tcdy6. The first
-two characters (the "salt") determine which of the 4096 passwords
-you will get. mkpasswd chooses the salt randomly, or alternately
-will let you specify one on the command line.
