I have a problem with using crypt(), passing only one parameter (ie, no
salt). When I do that, I get an empty string. When I do use a salt, it
returns the expected value. Does anybody have any ideas what might be
causing my problem? It only happens when I run it on my linux server, but
not when I run it on my Windows dev machine. Thanks in advance.
I am not sure what exactly is the problem. But check this from the manual:
If no salt is provided, PHP will auto-generate a standard two character salt by default, unless the default encryption type on the system is MD5, in which case a random MD5-compatible salt is generated.

Perhaps your PHP compilation or the package are broken.
