    NAME

    crypt.conf - configuration file for pluggable crypt modules
     
    

    SYNOPSIS

    /etc/security/crypt.conf
    

     

    DESCRIPTION

    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.  

    EXAMPLES

    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
