demos/maurice/README

-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.
