NAME

       crypto - The Crypto Application

DESCRIPTION

       The  purpose  of  the  Crypto  application  is  to provide message digest and DES encryption for SMNPv3. It provides computation of message
       digests MD5 and SHA, and CBC-DES encryption and decryption.

CONFIGURATION

       The following environment configuration parameters are defined for the Crypto application. Refer to application(3erl) for more  information
       about configuration parameters.

	 debug = true | false <optional> :
	   Causes debug information to be written to standard error or standard output. Default is false .

OPENSSL LIBRARIES

       The  current  implementation of the Erlang Crypto application is based on the OpenSSL package version 0.9.7 or higher. There are source and
       binary releases on the web.

       Source releases of OpenSSL can be downloaded from the OpenSSL project home page, or mirror sites listed there.

       The same URL also contains links to some compiled binaries and libraries of OpenSSL (see the Related/Binaries menu) of  which  the  Shining
       Light Productions Win32 and OpenSSL pages are of interest for the Win32 user.

       For some Unix flavours there are binary packages available on the net.

       If you cannot find a suitable binary OpenSSL package, you have to fetch an OpenSSL source release and compile it.

       You then have to compile and install the library libcrypto.so (Unix), or the library libeay32.dll (Win32).

       For  Unix  The  crypto_drv dynamic driver is delivered linked to OpenSSL libraries in /usr/local/lib , but the default dynamic linking will
       also accept libraries in /lib and /usr/lib .

       If that is not applicable to the particular Unix operating system used, the example Makefile in the Crypto priv/obj  directory,	should	be
       used as a basis for relinking the final version of the port program.

       For Win32 it is only required that the library can be found from the PATH environment variable, or that they reside in the appropriate SYS-
       TEM32 directory; hence no particular relinking is need. Hence no example Makefile for Win32 is provided.
