 of their letter is at the end.  The software can be compiled without  
 IDEA by specifying the --without-idea option on the configure command

 patent.  
   
 Date: Tue, 15 Aug 95 09:09:59 CET  
 From: IDEA@ascom.ch (Licensing Systec)  
 Encoding: 3001 Text  
 To: ylo@cs.hut.fi  
 Subject: Phone Call 15.8.95  
   
      Dear Mr. Ylonen  
   
      Thank you for your inquiry about the IDEA encryption algorithm.  
      Please excuse the delay in answering your fax sent 26.6.95.  
      Here is the information you requested :  
   
      Non commercial use of IDEA is free. The following examples (regarding  
      PGP) should clarify what we mean by commercial and non-commercial use  
   
      Here are some examples of commercial use of PGP:  
   
      1. When PGP is used for signing and/or encrypting e-mail messages  
      exchanged between two corporations.  
   
      2. When a consultant uses PGP for his communications with his client  
      corporations.  
   
      3. When a bank makes PGP available to its clients for telebanking and  
      charges them money for it (directly or indirectly).  
   
      4. When you use the software you receive from a company for commercial  
      purposes (telebanking included).  
   
   
      Some examples of non commercial use:  
   
      1. When an individual uses PGP for his private communications.  
   
      2. When an individual obtains PGP on the Internet and uses it for  
      telebanking (assuming this is approved by the bank).  
   
      3. When you use the software you receive from a company for private  
      purposes (telebanking excluded).  
   
   
      You may use IDEA freely within your software for non commercial use.  
      If you include IDEA in your software, it must include the following  
      copy right statement :  
   
      1. Copyright and Licensing Statement  
         IDEA(tm) is a trademark of Ascom Systec AG. There is no license fee  
         required for non-commercial use. Commercial users of IDEA may  
         obtain licensing information from Ascom Systec AG.  
         e-mail: IDEA@ascom.ch  
         fax: ++41 64 56 59 54  
   
   
      For selling the software commercially a product license is required:  
   
      The PRODUCT LICENSE gives a software developer the right to implement  
      IDEA in a software product and to sell this product worldwide. With  
      the PRODUCT LICENSE we supply a source listing in C and a software  
      manual. We charge an initial fee per company and a percentage of sales  
      of the software product or products (typically between .5 and 4 per  
      cent of the sales price, depending on the price and the importance of  
      IDEA for the product).  
   
   
      For further information please do not hesitate to contact us.  
   
      Best regards,
