This version of the libcrypt.so.1 library has entirely removed
the functionality of the encrypt, encrypt_r, setkey, setkey_r,
and fcrypt functions, while keeping fully binary compatibility
with existing (third-party) applications possibly still using
those funtions.  If such an application attemps to call one of
these functions, the corresponding function will indicate that
it is not supported by the system in a POSIX-compliant way.

For security reasons, the encrypt and encrypt_r functions will
also overwrite their data-block argument with random bits.

All existing binary executables linked against glibc's libcrypt
should work unmodified with the provided version of the
libcrypt.so.1 library in place.
