       crypt.conf - configuration file for pluggable crypt modules


       crypt.conf  is  the  configuration  file for the pluggable crypt architecture.  Each crypt
       module must provide a function to generate a password hash, crypt_genhash_impl(3C), and	a
       function to generate the salt, crypt_gensalt_impl(3C).

       There  must  be	at  least  one entry in crypt.conf with the same name as is stored in the
       crypt_algorithm_magic symbol of the module. The documentation  provided	with  the  module
       should list this name.

       The  module_path  field specifies the path name to a shared library object that implements
       crypt_genhash_impl(), crypt_gensalt_impl(), and crypt_algorithm_magic.  If the  path  name
       is not absolute, it is assumed to be relative to /usr/lib/security/$ISA.  If the path name
       contains the $ISA token, the token is replaced by an implementation-defined directory name
       that defines the path relative to the calling program's instruction set architecture.

       The  params  field  is  used  to  pass  module-specific options to the shared objects. See
       crypt_genhash_impl(3C) and crypt_gensalt_impl(3C).  It is the responsibility of the module
       to  parse  and interpret the options.  The params field can be used by the modules to turn
       on debugging or to pass any module-specific parameters that  control  the  output  of  the
       hashing algorithm.

       Example 1 Provide compatibility for md5crypt-generated passwords.

       The  default  configuration preserves previous Solaris behavior while adding compatibility
       for md5crypt-generated passwords as provided on some BSD and Linux systems.

	 # crypt.conf
	 1 /usr/lib/security/$ISA/crypt_bsdmd5.so

       Example 2 Use md5crypt to demonstrate compatibility with BSD- and Linux-based systems.

       The following example lists 4 algorithms and demonstrates how compatibility with BSD-  and
       Linux-based systems using md5crypt is made available, using the algorithm names 1 and 2.

	 # crypt.conf
	 md5 /usr/lib/security/$ISA/crypt_md5.so
	 rot13 /usr/lib/security/$ISA/crypt_rot13.so

	 # For *BSD/Linux compatibilty
	 # 1 is md5,  2 is Blowfish
	 1 /usr/lib/security/$ISA/crypt_bsdmd5.so
	 2 /usr/lib/security/$ISA/crypt_bsdbf.so
