Re: Unable to set ciphers string with space separated in apache

[William A Rowe Jr <wrowe@xxxxxxxxxxxxx>]

A good argument for following httpd documented convention.

If you want to continue exploring, you would want to quote the cipher string, since httpd would take apart unquotes, space separated tokens as different httpd directive arguments, and you surely don't want that.

Hi All,

  openssl standard says " The cipher list consists of one or more cipher strings separated by colons. Commas or spaces are also acceptable separators but colons are normally used".  But apache says "directive uses a colon-separated cipher-spec string consisting of OpenSSL cipher specifications to configure the Cipher Suite the client is permitted to negotiate in the SSL handshake phase" in https://httpd.apache.org/docs/2.4/mod/mod_ssl.html. 

So, when I configured apache by separating cipher string with spaces, cipher string has no affect.  But when cipher string is configured with colons, cipher string has effect. 

So, please provide clarification, is there any limitation why we can’t configure cipher string by using space as delimiter in apache.

PS: I am using 2.4 apache version in Linux OS.
