it's not clear what the acceptable characters are..
originally the [a-zA-Z0-9./] is the base64 set used
but the implementations tend to accept anything for salt
(it will go through some hash or encryption function
anyway, the only exception is '$' which is a separator
around the salt and maybe the characters used by the
passwd file format)
otherwise i'd rather be more strict with the input than
deal with weird corner cases, but i don't know what are
the practices (ie rejecting '=' or '-' is reasonable or not)
