+ | The < | ||
+ | different from most functions. | ||
+ | |||
+ | Given an arbitrary string and a " | ||
+ | returns the input string in a one-way encrypted form. This function | ||
+ | depends on the availability of a local crypt(3) library function. | ||
+ | the first 8 characters of the input string are significant. | ||
+ | is a two-character string, and may be composed of any combination of | ||
+ | any alphanumeric character, a period (.), or a forward-slash (/). | ||
+ | Additional characters may be available, depending on the crypt(3) in | ||
+ | use at your site. | ||
+ | |||
+ | ======Practical: | ||
+ | This function is primarily used for encrypting passwords, Unix style. | ||
+ | It is helpful if the input salt is itself sufficiently random. | ||

+ | ======Example: | ||
+ | < | ||
+ | $crypt(foobar ab) returns " | ||
+ | </ | ||

+ | ======Other Notes: | ||
+ | As mentioned above, this function relies completely on the availability | ||
