-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 irc.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. Just run
-mkpasswd, and at the prompt type in your plaintext password. It will
-spit out the encrypted password, which you should then just copy into
-the irc.conf file. This should be done only when adding new passwords
-to your irc.conf file. To change over your irc.conf file to use
-encrypted passwords, define CRYPT_OPER_PASSWORD in config.h. You will
-need to recompile your server if you already compiled it with this
-feature disabled. Once compiled, edit the Makefile in this directory
-and chang "IRCDCONF" to your irc.conf file. Then "make install" in this
-directory to replace all the operator passwords in your irc.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.
