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-1.07-crypt.tar.gz'. 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. Users outside the USA can get the crypt distribution via anonymous FTP from ftp.uni-c.dk [129.142.6.74], 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.uni-c.dk; transferring this distribution from prep.ai.mit.edu (or any other site in the USA) to a site outside the USA is in violation of US export laws.
