dispcrypt - encrypt a password, dispatching based on the
associated algorithm (Enhanced Security)

Security Library (libsecurity.so)
In order to quickstart a program, the program must be
linked as follows: -lsecurity -ldb -laud -lm
See the shared library discussion in the Programmer's
Guide for more information about using the quickstarting
feature.
The unencrypted password to be encrypted. A string value
which may be used as input to the selected encryption
algorithm. This parameter should be at least two characters
in length, and null-terminated. For password validation,
it should be the encrypted password which is already
in use. A value from 0 to (get_num_crypts()-1), indicating
which encryption algorithm is to be used. For password
validation, use the fd_oldcrypt field of an es_passwd
structure. For password generation, use the fd_newcrypt
field (and update the fd_oldcrypt field at the same time
as the fd_encrypt field if the change is successful).
The dispcrypt() function applies the specified encryption
algorithm to the given password string and salt value, and
returns the encrypted form of the password. The return
value is static data which is overwritten on subsequent
calls to this function or to the encryption algorithms
which it calls, so callers should save a copy of the
string unless the only use is an immediate comparison during
password validation.
This routine returns NULL if there is an encryption failure.
Otherwise, it returns a pointer to static data, which
is the null-terminated encrypted password result.
