This is the DES crypt() add-on. Install this to restore compatibility with existing /etc/shadow files, and to eliminate some quirks you'll get without it (like the "crypt: operation not supported" error when logging into a non-existent account). This package is kept in a seperate series/ directory (including the source code) to make it easy for foreign sites to decide whether to mirror it locally. In some parts of the world (France, for example) crypt() is considered too strong an encryption system for civilians to be allowed to have. You are responsible for following all applicable regulations regarding the use of this package. In most situations, there's not much need to install this. The "benefits" according to the included documentation are: * DES-based crypt(). This is only for backwards compatibility; for new installations the MD5-based crypt(), provided with the main GNU C library distribution, should be used instead. [But, if you are running an ISP that already has thousands of passwords in this format, switching to MD5 is probably not a viable option.] * The AUTH_DES RPC authentication method. In a given situation, this may be more or less secure than the AUTH_UNIX authentication method which is provided with the main GNU C library distribution. * User-visible DES encryption routines. Note that DES by itself is not now considered a very secure encryption method. To install this package, run this command as root: installpkg descrypt.tgz Note that if you install a new glibc binary package that does not include glibc-crypt and are running passwords in the old crypt() format, you will need to reinstall this package or you will be unable to log into your machine.
