The GNU C library now includes Michael Glad's Ultra Fast Crypt, which provides the Unix `crypt' function, plus some other entry points. Because of the United States export restriction on DES implementations, we are distributing this code separately from the rest of the C library. There is an extra distribution tar file just for crypt; it is called `glibc-crypt-2.1.1.tar.gz' (or whatever the last version is). You can just unpack the crypt distribution along with the rest of the C library and build; you can also build the library without getting crypt. You can get the crypt distribution via anonymous FTP from ftp://ftp.gwdg.de/pub/linux/glibc [134.76.11.100], or another archive site outside the USA. Archive maintainers are encouraged to copy this distribution to their archives outside the USA. Please get it from ftp.gwdg.de; transferring this distribution from ftp.gnu.org (or any other site in the USA) to a site outside the USA is in violation of US export laws.
