+From Maurice Gittens <mgittens@gits.nl>
+--
+ Example programs, demonstrating some basic SSLeay crypto library
+ operations, to help you not to make the same mistakes I did.
+
+ The following files are present.
+ - loadkeys.c Demonstrates the loading and of public and
+ private keys.
+ - loadkeys.h The interface for loadkeys.c
+ - example1.c Demonstrates the sealing and opening API's
+ - example2.c Demonstrates rsa encryption and decryption
+ - example3.c Demonstrates the use of symmetric block ciphers
+ - example4.c Demonstrates base64 and decoding
+ - Makefile A makefile you probably will have to adjust for
+ your environment
+ - README this file
+
+
+ The programs were written by Maurice Gittens <mgittens@gits.nl>
+ with the necesary help from Eric Young <eay@cryptsoft.com>
+
+ You may do as you please with these programs, but please don't
+ pretend that you wrote them.
+
+ To be complete: If you use these programs you acknowlegde that
+ you are aware that there is NO warranty of any kind associated
+ with these programs. I don't even claim that the programs work,
+ they are provided AS-IS.
+
+ January 1997
