Module: check_mk Branch: master Commit: a289dff1a63265a7d751741580647d22937ae5a7 URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=a289dff1a63265… Author: Lars Michelsen <lm(a)mathias-kettner.de> Date: Wed Oct 24 10:10:33 2018 +0200 6846 SEC More secure password hashing Passwords of local users of the Check_MK GUI are now hashed using SHA256 (salted, 535000 rounds) to increase the security of the stored user logon passwords. All existing users will still be able to login using their already hashed passwords. Once a user changes his password or a new user is created, these will be hashed using the new algorithm. Why SHA256? Check_MK supports different authentication frontends for verifying the local credentials: a) basic authentication (done by apache) and b) the GUI form + cookie based authentication. The default is b). This option is toggled with the "omd config" option MULTISITE_COOKIE_AUTH. In case the basic authentication is chosen it is only possible to use hashing algorithms that are supported by apache which performs the authentication in this situation. For best compatibility in all mentioned situations we use the SHA256 scheme.
